Yes, it is a problem as einstein2 appears to be an account use in conjunction with the recent hacking attacks against this site. He has been messaging people with a message regarding Buddhism or some such that contains a link to a site which attempts to install malware on your PC. There has simultaneously been an attempt to brute force passwords coming from a box hosted at an isp called theplanet.com with the IP 74.53.243.34

I believe several people have reported the abuse to theplanet and I think Reggie the ITT server admin blocked that IP. This latest report suggests that he may have forgotten to ban/delete the account or that the perpetrator of these attacks was able to recreate the account.
