Mibba Glitch or Was I Hacked?

Did anyone else get random 'HI' messages from themselves?

I got at lest 12 messages from myself; the same thing over and over and it only stopped once I changed my password. I just opened my Mibba yesterday and yet I had never shared or given out my password, let alone my user name.

I changed my password just in case but I was curious if anyone else had this issues?

Should I report it to mibba? Or just chalk it up to a issue with a glitch?
