Hey thanks for the response, infopro and SiteOx I do currently have reCaptcha enabled.
I've been reading over the threads suggested above I've yet to finish them but from what I've gathered so far is someone / some script is using an out of date SQL injection, I figured I might see some of this behaviour when I reviewed the query strings =? equals some number or something close. I did add a security question although I'm not sure if that will make any difference. it's seems the guy / script " DMASTERPIECE " has been doing this for quite sometime.
I will continue reading the threads suggested above and see what I can do to over come this issue, I'm completely open to suggestion and really appreciate them.
Thanks for the response
