I see what you mean, but the message doesn’t specifically promote it’s own books (which maybe says something about them??). If we block or ban or remove this one, then I think it’d have to be done for everyone who uses a website in their signature line. I don’t recall user names off the top, but the BootsNAll and BugEurope contributors here (sorry, I don’t recall specific threads) have been helpful over the years, IMO, and their messages have a link back to their websites. If they were advertising their own site, only, and the content of the message was not helpful, then at that point I think it becomes spam and advertisement. Just my 2 cents.

Sounds like a judgement call.
 
I’d say if the poster was putting links in his/her post to answer a questionfrom sommeone, then I’d say ok.  If a person is putting a link to a product in his/her signature, then it becomes a persistent effort to promote a product and can then be considered advertisement.
 
Looking at Europebackpack.com:
 
His email is:  europebackpack.com
Homepage is: http://Europebackpack.com
Signature: http://Europebackpack.com
 
A little too consistent for me.
 
Plus he only has two posts and both are for his site.
 
Next, look at the source code for his website.  You have two links that are for selling.
I’d say that it’s a little early to tell but it leaves the door open for someone to post helpful comments and have their signature as say: Amazon.com
    

Thanks, MB and Don.  Since the response was in-line with the original question and doesn’t appear strictly advertising, I’ll leave it.  I’ll post here if I see anything else from this “member.”

Good call OL.

Let’s leave it as is.  I think the general rule of thumb is to delete unsolicited advertisements with the exception of links in the the signature line.

Yeah, its very borderline.  The “member” (not sure why we are doing “that” but…) posted some pictures in the photo gallery too, which doesn’t seem like a spammer.  If anything, maybe pm them and ask what their intentions are and mentions what the rules are, sort of a non-offensive warning.
