Nice plugin for Gravity Forms to block harassing creeps

Thanks for this free plugin, for the ability to mark an entry as spam by creating blacklists. 50 black lists with 100 items per each is quite generous and typically enough.
All other functionality is PRO paid version, but still was helpful for my needs, as had a sicko lowlife client thief trying to get hundreds of dollars worth of our goods for free. PayPal closed his fake cheat claim and chargebacks and he attacked again and again and began pounding with dirty filthy emails that passed honeypot and other spam email plugins.
Thanks to yours I could create a list with his 8 frequently used filth and block him from submitting.

Thank you!
