A lot. Over the past 10 or so years...some of the names I can't remember but some are Ethereal RO, HeRO, EpicRO,TalonRO and so many more. Since I started playing RO again this past few months after being on a 5 year hiatus it's been mostly low-mid rates and now on a low rate server called Ragnarok Reborn ( Which is an amazing server, I think I finally found ''the one'' lol. )
