Wtf gaia ?

I tried Charles on gaia auth and when i was wondering around I saw that it posted this :

[b][u]forum.logicalgamers.com|utmccn=(referral)|utmcmd=referral|utmcct=/redirect-to/[/u][/b]

along with other code but the part that got my attention was this.

WTF ? Do they get my opened tabs or something ?

Any idea on what happened ?
