Has any high level contributor been banned because of their "Not Received" giveaways?

Yeah, as soon as GTAV pops up, I just assume it's a scam. Never quite understand the intent of the giver.

Sounds reasonable.

I think a proportion system rather than a total number would make sense. Like if someone has 40 not receiveds but has hundreds of giveaways that's very different to 40 on someone that's done 60.

Thanks for the comment, I would think the same.
Just wondered if all those people I asked, have any basis for their fear of a ban, since all of them were legit high level contributors.

People that do such stuff, don't do it only 1 time, so at some point it is so obvious that they recieve a punishment.

If i remember correct, got 5+, all high level, users perma suspended because of my tickets because of such stuff.

I imagine having giveaways marked as not received is a quick way to find oneself in a bunch of blacklists, so it makes sense that people will try to avoid that as much as possible

Fair enough but none of the contributors I've asked presented this argument.
Leveraging group GAs for potentially bad keys, when one wants to keep a clean ratio, is a great idea, IMO.

Friendly people accept a deletion, if it is visible that the gifter don't started with a bad intension.
But the a$$holes will not accept it, whatever the group rules are.

In my group it isn't listed as rule like "you must accept a deletion" but because it is/should be normal human behavior we had only one case, in all the years, where a member don't accepted the deletion (and got blacklisted for this from the gifter and a few other ones...).

As example my 2 "not delivered" stats came because one, low level, winner in one of my, public, cakeday threads not reacted on my question if he would allow the deletion of a GA were the key wasn't ok (if i believe his words). I wanted to offer him a other small game as replacement but he never reacted on 2 messages from me and marked it as not recieved after 7 days.
The second one gave me a winner that told me, after 4 days, the first key isn't ok. I replaced the key a few minutes later and wrote him that he can test the next key, he done this and wrote me again 4 days later. I replaced it with a third key and he wrote me, again, after 4 days that the key wasn't ok and that he don't want to try more keys (i still had 4). Nearly all other keys from games that i had from the same source and gave away at the same time were ok, so it isn't 100% sure that all 3 keys weren't ok but if so, i would had be able to replace the key 4x more, so the chance for a working one was nearly 100%. And that this user needed always 4 days to test the next key and to write me, i replaced each key only minutes after his messages, let me extreme strongly assume that he was a multiaccounter.
The marks frustrate me because i had still keys for the second and got a bad cakeday "present" from the first (i don't do cakeday threads and GAs anymore as result from all the negative stuff that i had each year with the majority of the winners) but i learned to ignore it and don't care anymore if there is a 0, a 2 or a 30.

Thanks for the input!

If they want to replace the key, that's fine. But if they say "I don't have another key, can we delete?" I'll say yes. You don't know that person's financial situation and it doesn't hurt to show a little kindness.

In this context, why is it not kind to just mark as not received and move on, which is how the site has always worked?
I get that it's considered a stigma or whatever one may feel like for some contributors, but why should we bash/criticise a winner if they have a different opinion on how invalid keys should be handled?

Otherwise, it would be like saying "if you can't afford to buy replacements, don't make GAs here." I don't want anyone to have a mark on their profile if I can help it.

In the end that's what it boils down to, I guess. I wouldn't phrase it like that though, since it makes the winner look like they have ill will.
If you can't afford a replacement, then you just have to live with the non-received marks. There are groups where one can join to have members always accept GA deletion.

Solutions exist, it's up to each side be kind enough when resolving such situations. And accepting the other side's opinion when it's different! If one does not accept deletion, it doesn't imply they want/like to be mean.
