I’ve noticed an increase in smarter spammers, over the past year or so. Instead of posting 10 links to a porn site which quickly gets deleted, they post a legitimate sounding post, and then have a link in their signature which is spam. Even more recently, there were some posts where the spammer initially had a blank signature, but days later (after the thread fell off the portal), went back and edited their signature.
One example of the latest method is still in the career forum. http://www.chiefdelphi.com/forums/showthread.php?t=86609 It was posted on the 16th with a blank signature, and the spam link was added on the 20th.
Other recent spam posts have had just one line that says something like “I agree with you”, or have copied parts of previous posts so that if you skim it, it seems reasonable, but doesn’t actually make sense. Others have asked legitimate (but unrelated to FIRST) questions, like this one (look a the link in the signature): http://www.chiefdelphi.com/forums/showthread.php?t=86607
These spammers don’t even care if you click on their link. They just want as many links to their website as possible, so that they show up higher in search results.
One way to determine if a post is SPAM is if you notice something that seems odd, copy a part of the post and search Google for it (you can use up to 32 words), using quotation marks to enclose the quote. If it shows up in more then a few forums, most likely it’s a single spammer operating across the internet.
One forum I frequent recently decided not to allow new users to post links in their signatures until they get 10 posts. Presumably, a spammer wouldn’t post 10 times without someone catching on. That might be one way to limit the affects of this type of SPAM.
For those who may be new to chiefdelphi, if you see a post that is spam, you can use the report post button in the upper right corner of the post (it looks like a triangular sign with an exclamation point). This will report the post to the moderators so they can review and delete the post if necessary.
I don’t think that Spam is a huge problem on CD, but I don’t like to see spammers able to get away with anything.
