Weird messages popping up in-game

I don't really know why that happens but it doesn't matter if you click Accept or Decline. Can you tell me the exact URL that shows up when you press Accept?

Ya it happens to me too. I just decline it.

It happens to me too, the linkids for me is always the same, it is like ????????? (Its question marks in diamonds)then a few letters.

It just happened to me to! I thought it was a link to a virus so I egnored it!

This happens in other servers also, not just Freezzer. I believe it's a bug with the URL plugin. It can get annoying at times though lol

Showed up for me too, the url was au(space) Ut

Then went to blank:blank

Just ignore it or send me the links if you press 'Accept'.
