Alentejo and Algarve made a genuine attempt at commending his region, but the proposal was marked illegal. In response, Alentejozinho and Algarvezinho (different person) submitted this proposal to the SC and posted it on the SC forums, essentially giving the quintessential soapbox about how the moderators and WA elite oppress people and such. Anyone who reads that thread can see that it is obviously just intended to bait people: calling people arrogant and self important, mocking Sodoran Alesia ('hilarious' is used negatively ofc), saying some condescending crap about how we take this game too seriously, posting the proposal just so we can "shoot it down", calling people hard-asses. It's easy to ignore someone like this when they stick to their own thread, but they haven't had their fill and have decided to encroach upon a serious thread where his baiting would be much less welcome. Incidentally, that thread is where he made his most obvious baiting post yet.
Now, not all of these posts are blatantly illegal (the following probably are tho: viewtopic.php?p=38162254#p38162254, viewtopic.php?p=38159229#p38159229, viewtopic.php?p=38159278#p38159278). The problem is that this player has contributed nothing, shows no sign of ever contributing anything, and his entire presence on the SC forum has only been in the form of trolling/baiting. I think we can therefore make the distinction that he's a troll (intentionally), and not a genuine player with character issues. You'll note that he claims to have played "since the beginning", but still uses a nation with a 50 million pop to do his trolling— if he's looking for anonymity, he knows he's trolling.
Alentejozinho and Algarvezinho shows no sign of ever contributing anything to the SC forum except to troll. In the very least, I think he should be warned for the markedly illegal posts (viewtopic.php?p=38162254#p38162254, viewtopic.php?p=38159229#p38159229, viewtopic.php?p=38159278#p38159278) and his thread should be locked, given his acknowledgement that it will never pass and what he's using it for. I'm not sure that will deter him, given his attitude to the game, but it's worth a shot (and he's trying harder because no one will bite).
Edit: He could also be DoS, given that he recently made a new nation.
