I have noticed new members that crop up who are just playing pranks on their posts with advertisements for shoes and the links have malwares in it (my antivirus tells me that a trojan was blocked)
Theres one that got blocked right away as he was posting pictures of girls in thongs...very smart of that forum staff to have detected it right away.
Now I am wary at welcoming new members or answering on their posts for fear of being compromised.
