Was this someone trying to hack?

[meissenation]

I received two database error e-mails and both of them have the same content - I changed the text to red for the part I'm worried about. It looks like they were trying to inject base64 code inbetween the IMG tags.

I also noticed that the IP address does not match the IP address in the profile for HotRoddCamaro. I did a search of users by IP address with a depth of 2 and it didn't find any matches. I did notice the IP address is local and isn't a chinese address.

Was this someone doing something suspicious as it looks? Base64 in an img code? Just wondering if I should be doing an IP block.
