allanit on "404 error in log files"

Hi guys

In the past few day I have been getting a lot of /++liker.profile_URL++ in my sites log files which is causing the 404 error. I can't find anything much in the way of help from google. I also want to acknowledge that this may have nothing to do with wordpress or any plugins but because I can't find an answer any where else I thought I would see if anyone here could shed any light on what could be causing /links/++liker.profile_URL++ in my log file.

Thanks in advance.
