My dear friend, since it is Valentine's Day, I say this with a lot of "heart" and love for you and your partner/friend:

I am not a security expert but security is a very important issue. I am not sure what framework you're using (most likely no framework), but being anonymous AND able to post as ANYONE is a serious issue (well, your user list only goes up to about 6 people--0 being unknown and 1-5 are somewhat real users; user # 4 user is deleted perhaps). One thing you can do is to check if the user posting is actually authenticated and really who s/he claims to be.

Your infrastructure is too fragile and amateurish. Obviously, haters are gonna hate, but believe me when I say, this hurts me more than it hurts you. Take (all) your apps down and then do a security audit on all of them before you hurt yourself.

Happy Valentine's Day.
