Entries on Giveaways for Suspended accounts

Yes for me as the person entering wont know if the creator is banned unless you check which I know I don't for almost all my giveaways.

Of course they should. Even if they win they can't never release the feedback, so you should bug out support for either changing the feedback or requesting a reroll. Automatically removed entries would be a win-win for everyone.

automatically? nope, because there is a case of human error (support stuff missclicking, permabanning when he wanted to do 3day ban, yet all entries were refunded already) as well as appeal (unless you get permabanned instead of permasuspended you can always appeal and open unsuspend ticket, there were cases of people getting unsuspended this way).

But there should be a warning system - if GA creator gets suspended entrants should get a warning and decide whether they want to leave GA or not.
