Exactly, I don't get it either. I don't see the need for the change, and any google search I do brings up people asking the same question. The answers are usually, "I don't know, but its probably due to RMT spammers and BLM's doing WP" or something similar. So I'm asking here, on the official forum, "Why?" Because Reddit (the place others are asking) doesn't know either and I wouldn't trust them anyway.
