Nothing is for sure with IT, sometimes you just have to keep trying different things until it works, even if you are expert. I am no expert on website security, but I am able to identify the offenders and keep trying blocking techniques until it works. There are several additional techniques yet to be tested. We may even move up a planned move to another more secure hosting platform, real soon.

FYI. We could license software or use a service to eliminate the offenders, but it would cost well over $1,000/month. We are trying to use the security features available within the website before we have to spend on a solution.
