How can they bypass Captcha? o_O
I can confirm never seeing any gold sellers in GW2, well I only played to lv15 but I spent some time in the capital
Whereas in WoW, aside the usual anal "jokes", carry run sellers (same as in FF14) and guild recruitment, you also have gold sellers in trade chat. Of course those also bot, hack accounts and whatnot. It's just less blatant since the world is so huge and there are many players.
Oh, and Alterac Valley & Isle of Conquest are FILLED BY BOTS on Horde side (100% lose rate, 100% free win guaranteed for Alliance there) whereas Alliance has teams of bots in Silver Shard Mines & another BG I forgot, didn't play since after WoD's fiasco launch and dissapointed new features (or lack of).
FF14 is really not that bad. I'm pretty sure SWTOR also had gold sellers, since after the free to play change.
In FF14 I don't see any more than one gil seller message per day, max. I used to see more some weeks ago.
I'm on Odin and I'm pretty sure it's the most populated EU Chaos Data Centre.
Housing has some small plots available but M & L plots still cost an arm & a leg, that's why there are gil sellers. Also because of the high demand for materias and alexandrites for Relic. Which are also a huge waste of time and gil sink lol (opinion)
It seems that SE is indeed removing them. I removed all the gil sellers from my Black List and didn't see them again so yeah.
