I understand that:
1) that Christos kid apparently got that Elekid from a site where redistribution is handled much more loosely, so he may have actually not understood that it wasn't fully redistributable and
2) he's new to smogon
so I kind of doubt he was doing anything purposefully nefarious. But he did trade it without rights. At the very least I would suggest that he needs a stern warning (not an infraction) to let him, and hopefully others, know that he must verify the redistribution of any mons he trades here.
I didn't want to post in the Blacklist thread because I'm not a mod, and I don't want to give him or anyone else the wrong impression. Just my opinion (coming from a guy with only Fully Redis mons hahaha).
