WGT take harassment very seriously. I have encountered certain members whose behavior is intolerable (polite way of saying disgusting pigs...). I give the warning to please stop or I will take a screen shot of the chat and send to WGT member services. If they persist, which they always do, I take the screen shots, paste them in a word doc, and send them to WGT explaining what happened.
In every instance, the member has been suspended. Although WGT will not advise you of the result of their investigation, I simply wait a few days and then search the player in the community link. If the member is suspended, their player name will not be found in the search.
All in all, for the most part, the WGT community is a bunch of great people.
