Hi @bcarney
Thanks for contacting us and sorry you are still having some issues with spam even with reCaptcha installed. I have noticed this happens occasionally on various sites. We have even been the victims of manual spam attacks that can’t really be prevented with most automated spam protection.
We don’t have anything built into Formidable that can specifically block Cyrillic text, but I would recommend adding common words from spam emails to your WordPress comments blocklist. All form entries are checked against this list.
There are additional layers of spam protection you can add—Akismet works well for us. I have also heard good things about the anti-spam plugin by Cleantalk.
These tools are all documented here: https://formidableforms.com/knowledgebase/add-spam-protection/
Hope this helps and let us know if you have any further questions on this.
