Yeah, that's because they were designed to be used with AIM, ICQ, MSN and Yahoo! These were legacy chat applications that were used before Discord, Telegram or Signal became mainstream.

It seems that trying to modify XMB's templates are all bjorked so these won't work. The only working profile is your website.

Sucks, cause I made cute little buttons for them all.
Just copy and paste the text or something. Clicking them will do you no good.

ICQ also only takes numerical inputs, cause your usernames were only numbers. So uh, if you enter a number in there... Meow!
