i agree with you. back when i was running the name changes, it was my idea in the first place to switch from 4 months to 6 months. it's obviously been changed back since, though; the admins these days seem more lax about it than before, and i guess 4 months worked out being more popular. people like name changes, i guess. no big deal really though!
honestly i never really liked them myself; had a couple but i'm pretty happy just staying with the name i signed up with in the first place. tbh i can barely even recognise anyone any more with the rate that the changes happen at now - particularly not people who get them any time and don't need to wait the full 4 months. but i'm a grumpy old man and if i had it my way, there'd be no changes at all, haha.
