As someone who is familiar with the developers of the programs you mentioned, and as someone who develops my own scripts for account registration, I can say that it is a combination of factors that influences the outcome. Several factors have been correctly identified here.
If you simply register an account and leave it on hold, the fact that it will work well depends on some realistic activity, warming up, and maximum human-like behavior, as much as you can replicate that.
Then, it is also important how you start sending messages afterward. If you just launch the account and send messages directly, that is not effective. However, if you wake the account from its slumber, so to speak, after the waiting session, and begin to warm it up a bit - engaging in some activity that is somewhat unrelated to direct messaging - then when you do start sending direct messages, it can have a positive effect. Many find that this helps in blurring the patterns that can easily be identified by AI.
Since August 2025, of course, everything has become much more complicated. The work with autoreg accounts has changed quite specifically, and even when you use such accounts on real phones it’s unstable and can cause “Confirm You Are Human” bans.
