The staff is not acknowledging or responding to most problems like this. All we can try to do is go to: http://www.last.fm/music/+noredirect/Vesala and click yes on the right hand panel where it says "Is Vesala the correct name for this artist?". It probably doesn't even do anything since the site is so terribly designed now but I guess it's worth trying.
Don't get your hopes up when it comes to fixing these shitty redirections. When the redirection/auto-correction feature was first announced years ago, it was kind of promising due to all the litter everywhere from people mistagging their music and so forth. Of course the designers were incompetent and massively botched the way it works right from the start. However, you used to be able to disable the feature which was essential. It still exists in the settings, but it hasn't worked properly for a very long time. Thanks assholes. At this point the core of what the site used to be (listening statistics) is in ruins thanks to "out of control" garbage just like this.
