There is a gametracker page of mine with a name associated with my account. people keep finding it trough googlin my username on which i am really annoyed..
I joined a WCFAN clan server once and since then the gametracker page is saved i cant associate it with my profile for some reason .. what to do?

If you are referring to an account you can log into it and delete it on http://www.gametracker.com/account/manage/edit.php

If you are referring to a player name in the history of a server, you will have to contact the owner (or the person who claimed the page) of each and every server and request they delete the stats for the profile you want them to. They would not be under any obligation to do so.

Noo.. see thats the thing i never ever joined this website until i found out about it by randomnly typing in my username (not gamertag, i typed in my email adress name before the "..@emailprovider.com")
and it shows up this page.. now i wouldnt be concerned if this wasnt my email adress i am using for work and stuff.

I must have changed my name to that email name for a few hours which i usualy do since games like dead island do not recognize symbols, which is pretty normal on my account ( i use alot of symbols in my name)

I just want this account to be deleted from this website
http://www7.gametracker.com/player/rf.soylu/89.163.166.151:27025/b/
or at least change the name.

You will need to send a message to the owner of that server page which you can see on http://www.gametracker.com/server_info/89.163.166.151:27025/ requesting that they reset that individual player. Please keep in mind the owner would be under no obligation to do so.

As you confirmed, it's not an email address or anything like that because it does not have a domain name or anything attached so you should be good if you're not able to get a favorable response from the owner.
