I believe I found the casino code, and it may be possible that this has injected other code on my site which I've already had to remove and during a backup AVG also found a backdoor trojan.
There is potential this also added several meta tags to my website, not the wordpress install. the tags were raunchy. It's too bad this developer is writing code to be malicious. Shame on the developer.
I got hit in a couple locations but this is one I suspect may have caused my problems which could be bigger than anyone's seen from this plugin. Since I can't know for sure I'd just definitely warn to be wary of this particular plugin.
