Thoughts on removing these offending threads? They serve no useful purpose, especially given these reported intrusions.
I think it happens on any thread at random so deleting offending threads wouldn't work. This one is not necessarily to do with links. Well that's what it seems to me anyway.
Nope, just any thread where you're redirected thru clicking on a link and the browser hijacked or misbehaving with popups. Granted I don't know the full extent of it but seen enough to warrant a rollback to find out who has had what trouble with what links and what threads and dump them. Nothing to do with any member at all. That is one reason I never look at links ....
But I don't think we can assume that any threads where this is happening is caused by a spammer on the thread. & selfishly I would rather that my thread with helpful information for me wasn't just "dumped" because of a technical glitch, if possible.
