And you know why? Because trolls want to ruin guilds. Of course they will spam request the ability to easily bully others and so they can abuse the system. This is like saying building rotation is one of the most requested features. Or an Aid all button. So many features have been requested by a lot of people.
People keep thinking so incredibly selfishly here, that's why they are the posts with the least +likes. They only thinking for themselves, to change their name once, not thinking of the bigger picture. As long as you put in a way to tell who changed their name/their previous names (why is it "names" now, since they can change multiple times with no consequences or CS help?)
We've just kicked 3 people from the guild this gbg season cause after countless warnings for being trolls in gbg and rogue's and slowing down our farming for days, now they can just change their name, come back in and do it all over again? Why would this be a good thing?
