How often do you reroll for winners?

Try giving away to slightly higher levels to avoid the bottom feeders

I usually have to reroll about thirty-forty percent of my no restriction giveaways, almost none of my 6+ giveaways, and a surprising amount (at least 20%) of my 2+ giveaways. Depends on the level range.

I try not to reroll after i send the keys, cause there might be complications if the first person uses the key :)) So i had to wait 3 and a half weeks for someone to activate :)) I'll wait even longer if need be :))

So far, I've only had to reroll 3 out of 38 (so about 8%) of my giveaways. One reroll was requested by the winner, one was because of unactivated wins, and the third was a group giveaway and the winner was no longer part of the group. I can't say if it's luck or a growing problem though. I don't think that I've been around long enough to make that call. :)

If there is an infraction, always if its within last 2 years.
Out of 1222 giveaways I have 161 requests for new winner. 30ish of those are bacause winner asked me to or something like that. Of course lately I have settled on lv2 as my minimum for public giveaway to minimize support workload.

I'm trying to reroll one but waiting response D:

Very rarely. Happened maybe 2-3 times in my whole SG career.

I tried to reroll once because somebody was being a dick, but that wasn't allowed unfortunately.

I only rerolled once , when one of my GA ended the user had already the game in his library so i asked for a reroll and it was a quick one. Till now except once i never had any problem with my winners with non activating or marking recieved

Usually when the winner has unactivated wins, happens almost everytime I do a public giveaway :D

Maybe till they were able to pick my name? hahaha xD
Is there a way to know if you have won a game but has been re-rolled to another user?

never, I don't care if the winners are rule breakers

I've only ever re-rolled once and that was because the person who won had won the same game from someone else the previous day and hadn't gotten around to un-entering other giveaways. No big deal.
