Regifted vs. Fake

Because checking for regifts is easy to prove. Calls of 'Fake' aren't always right. Private inventories and key sites alone prevent that.

I guess no matter if its true..its calling out. But best way is to report regifters to support..but they are busy, dont expect an answer until new year xD

why do you even feel the urge to comment? there's "Report" button. Click it and move on =)

If you truly feel like it is breaking the rules either way then report them and see what support decides. It is really up to them anyways.

Someone called out a giveaway I recently won for being fake, didn't make it fake though.

Mods explained me their definition of their concept of calling out® as shouting publicly that an individual broke the rules. So doing for fake or regift is the same basing on their explanation. Anyways that part of rules NEEDS a much better definition.
There's a problem on the judges part, because sometimes is hard to define if the user is calling out or just reminding the rules, as where you asked initially.

What about calling out for regifting a fake giveaway?

And for what reason do you want to risk it? There's no need to cause trouble.
