Contact Form is blocked

Hello to the team !
Sorry for my crapy english but my contact form is blocked. no one can sent me something.
I’ll try with different computer or mobile, even my customer are blocked. Is there a way to restore defaut setting ? I think it’s coming from the tips “Cyrillic Spammer” or something like that, i’m not sure. Anyway, it’s a dead end to me. Best regard.
