On the surface, the services described above seem to be all good. Most of them claim they offer real followers. However, if you dig deep, you will discover that they are being economical with the truth — most of them offer bot followers.
These followers at their best, do not engage — at their worse, they do but the engagements are full of spam. Not only that, TikTok as a platform discourage getting followers via these means and as such, the algorithm is designed to detect and remove them. If you use the services excessively, you can get suspended.
