The account lasted three days, then got banned or shadowbanned without explanation. Sound familiar? Most people think it’s the proxy or the content’s fault. In reality, accounts get shut down earlier-even during the warm-up phase-due to simple mistakes that Instagram and TikTok’s algorithms learned to detect back in 2024. In 2026, anti-fraud measures got stricter, and the cost of a mistake is your entire warmed-up account pool. Let’s break down exactly where accounts get flagged most often.
Mistake 1: Starting activity too quickly
A newly registered account can’t behave like one with a history. But that’s exactly what people do-immediately after signing up, they upload a profile picture, write a bio, follow 50 people, like 200 posts, and post their first Reel-all in a single day. To the algorithm, this is a classic bot pattern.
For the first 24-48 hours, the account should just exist. Log in, scroll through your feed, watch 10-15 videos all the way through, then log out. On the second day, add a profile picture; on the third, add a bio. No follows or likes for the first two days. It’s boring, but it works.
Mistake 2: Linear and Predictable Pauses
Bots operate on a schedule: like-30-second pause-like-30-second pause. TikTok and Instagram’s algorithms have long been able to detect uniform intervals. A real person watches videos for varying lengths of time, scrolls quickly, then pauses on a single clip, leaves the app, and comes back.
If you’re automating your warm-up, randomize your pauses-don’t stick to a 28-32-second range; instead, vary them from 15 seconds to 4 minutes, with sessions of different lengths. Alternate short 3-5-minute visits to the app with longer 20-30-minute sessions. Mimic a real person, not a script.
Mistake 3: Using a single proxy for multiple accounts during the warm-up phase
This wipes out entire batches of accounts at once. If the platform detects that five new accounts are being warmed up from a single IP address, all five come under suspicion. One gets banned, and the flag spreads to the rest.
The rule is simple: one account-one dedicated IP, and that IP must not change during the warm-up process. The best option is mobile or residential proxies with geolocation that matches the account’s profile. A data center from 2026 used during the warm-up phase is almost a guaranteed red flag.
Mistake 4: Posting content before the warm-up period is complete
This is the most common mistake made by those in a hurry to monetize. The account is only 5 days old, the warm-up isn’t finished, and yet the first post or Reel is already going live. Instagram and TikTok evaluate the engagement of the first piece of content-and if an account with no history has zero views and interactions, that’s a red flag. The algorithm won’t promote the content and will flag the suspicious pattern.
The minimum warm-up period on Instagram before the first post is 10-14 days of active behavior. On TikTok, it can be done a bit faster-5-7 days-but only if the behavioral trail is convincing: views, comments, and follows of relevant accounts in the niche.
Mistake 5: Ignoring content engagement during views
Warming up isn’t just about follows and likes. The algorithm looks at exactly what the account is viewing. If you’re posting, say, fitness content, but during the warm-up phase your account views a random mix of cooking, politics, and cars-the algorithm’s interest in your account will be low.
Build a niche-specific behavioral profile from day one. Watch content in the niche your account will focus on. Follow the leaders in that niche. Leave topic-related comments. That way, by the time you make your first post, the account will already have a clear profile of interests that the algorithm can understand-and your first content will receive relevant exposure.
Mistake 6: Changing devices or proxies in the middle of the warm-up period
Platforms link an account to a combination of device, IP address, and behavioral patterns. If you change your proxy or switch the account to a different phone in the middle of the warm-up phase, the platform detects an anomaly. This is especially problematic for Instagram, which has long since mastered device fingerprinting.
Rule: Once you’ve started warming up an account on a specific device with a specific proxy, don’t change that combination until the warm-up is complete. If the proxy goes down, it’s better to wait and reconnect to the same IP than to connect to a new one.
Mistake 7: Zero activity at night and on weekends
A real person sometimes uses TikTok at 2 a.m. Sometimes they get hooked on it for three hours on a Saturday. If an account is active strictly from 9:00 a.m. to 10:00 p.m. on weekdays and completely inactive the rest of the time-that’s the pattern of a bot, not a real user.
Add occasional late-night micro-sessions-once every few days, for 5-10 minutes. On weekends, slightly increase the length of your sessions. It’s a small detail that makes your behavioral profile look less artificial.
To be honest: everything described here applies only to accounts that you control yourself. Automating account warm-ups and using multiple accounts violate Instagram and TikTok’s rules-these platforms are constantly updating their anti-fraud measures, and there are no guarantees that your accounts will survive. Proceed at your own risk.
Checklist: What to Check Before Your First Post
- The account must have at least 10 days (Instagram) or 5-7 days (TikTok) of active behavioral warm-up
- The IP address has not changed since the account was registered
- Pauses between actions are randomized; sessions vary in length
- Viewed content must strictly align with the niche of future posts
- There are nightly and weekend micro-sessions in the activity history
- Initial content is native, with no links and no aggressive CTAs
- The device fingerprint has not changed during the warm-up period
When you have 10 accounts, you can track all of this manually. When you have 50 or 200, the human factor takes down more accounts than any algorithm. Lusiesta lets you keep your entire account pool under control: the right activity rhythm, the right proxy for each device, and the right behavioral scenario-all without having to manually monitor every account. Scale without chaos-that’s the essence of this tool.
