@Vancieri, You have to change your password to get rid of it, there's a more in depth process on how to fix the problem in this forum post: https://steamproxy.net/discussions/forum/0/3821910883991377775/ also did someone on your friends list start sending you the "catch 50$" message before your account started sending these messages? If so, you might have to unfriend them so that it won't happen again.

how did you fix the "catch 50$" problem? i have it too
