If you use some proxies that are highly flagged or used for crime, jagex will lock accounts logged in from them. Maybe time for some new proxy's/Company.
If they have evidence of you've botted on same IP/Host or used same emails for the account or in any way link them together, they will most likely be a perm ban first time. As far as I've encountered.
Yeha kid was edgy as fuck, I knew something was terrinble wrong when he outta nowhere asked if he could buy 100M 07 off me. Glad I didn't sell him a single gp.
I had the feeling, yeah. Asked me if he could buy 100M 07. But afetr being a duché I denied and told him to fuck off. Damn, I'm so sorry for anyoen who got scammed by that fucking shit cunt.
