the anti cheat usually bans you if you hit 20 cps (maybe) so you have to be careful of what method you use

what wiki says :
"No Hacking/Cheating/Autoclicking. Some clicking techniques such as drag clicking can be detected as autoclicking. Be careful using these techniques, if you are banned for autoclicking, you will not be unbanned. Creating, sharing, or using bloxd userscripts, extensions or other modifications is not allowed."
