Is it possible that, by doing so, we can pick up viruses or cookies that we don’t care to recruit?
Possible? Of course. Likely? Not in my opinion. The pros doing real evil use better methods than spamming forums and the script kiddies can’t be bothered to do the actual work required to spam forums. Even with automated software, it takes time and effort and money. There are easier and cheaper ways to find those who can be preyed upon.
Besides… haven’t you heard? The web is dead. It’s all about apps these days.
If so, should we not warn Forum members of this possibility?
