The Report Abuse button itself, as far as I know, is dysfunctional. It throws up an error page after you use it to send a report. You probably need to send an email to members@worldgolftour.com instead.
I'm a big enemy of deleting old forum threads. Deleting old forum threads is a sign of amateurishness and disrespect for forum participants. Every forum should be proud of its history & showcase its old threads. Of course, old threads may get locked, bu they should never, ever get deleted. These days, server space is cheap, so having text-based forums archived forever with all of their history is a ridiculous trifle not worth mentioning.
Fortunately, WGT do not delete old forum threads, and I hope they never will. 
However, what WGT sometimes do, and it's very regrettable, is that because there are no designated forum moderators here, sometimes entire recent threads, with many legitimate, carefully worded posts in them, get deleted without reason, warning, or explanation. That is an extremely amateurish thing to do, and adds to the many problems in these forums, the many functionality bugs. Let's hope that, in future, whoever the anonymous person in the background is who does these deletions, will only delete offensive posts, rather than entire threads, carelessly.
