Ok so if i have 2 accounts banned for hacking or something and i bought unban for my main account will i be banned for ban evading all i really want to know .
You won't be banned for ban evading you'll have to wait for your alternate accounts to be unbanned or pay for an unban on the alts.
We wouldn't want to ban you again since you bought an unban. But the Staff can't keep track of everyone who's banned on multiple accounts and buys an unban for 1. So if you do end up getting banned for ban evading, just make a ban appeal including proof that you bought an unban.
