Bots playing my game ?

Hello, I've recently (like literally 1-2 days ago) released an incremental game I've been working on for a bit, I've been running some ads to test some metrics like the CTR of my ad. What I've come to realize is that for some reason there seem to be what I believe to be bots joining my game and essentially ruining any statistics I'd hope for my game to achieve, they're just joining and either doing nothing for about ~1-2 minutes then leaving or just straight up leave after ~30 seconds, it's always the same type of name where it's just "<name>_<number> or <name+number>", with similar names and overall semi-fresh accounts with no cosmetics or anything of the sort, consider my game is 16+ since it is new, I find it pretty hard to believe there would be this many people joining with extremely similar names, quitting almost instantly despite a VERY easy to follow tutorial (~2 minute tutorial with only 10% of people finishing it) and with "bacon" accounts. Has anyone else also had this issue ? Is it some sort of like automatic system for checking TOS violations ?
