They could just check the ban date of the accounts right and see that they were not banned after the update ofcourse if like 300 people do it just saying then maybe some accounts would get unbanned but don't think it will work personally
Slayer is a decent way to train combat yeah but people mainly do that to make money off it afterwards plus you could get bad task that will decrease your xp rates so nmz all the way
i found that there was no difference i had a pure and i wanted some easy afk money so i botted cannonballs and i never botted on my account before and i got banned in a couple hours
