In the last two years, the number of services that provide cheat bots has sharply decreased. YouTube monitoring algorithms have learned very quickly to recognize cheating bots and began to react very harshly to it. Previously, vloggers could still calm themselves with the fact that the ban for such actions is rarely imposed, the author will simply lose the inflated subscribers. Now it is more than possible to get a strike (warning) for cheating. This is especially true for channels with monetization, YouTube watches them especially closely and punishes them more severely. And as we remember, after the 3rd strike, the channel will be permanently blocked. Today, they mainly offer services for cheating subscribers of the second type — exchange. Such services bring together people who are interested in promoting their channel. These people subscribe to each other's channels, and thus increase (as planned) the number of subscribers to channels at the expense of "live", working accounts. It is assumed that YouTube will not be able to track this kind of cheating, so it, cheating, is supposedly a "safe" and almost "white" way of promotion. In fact, this is certainly not the case.
