Hi, so I had this problem to our site that allow users to enter their marketing promotion through our contact forms. Is there any free plugin that is compatible with ninja forms to prevent that? Or any ways in general to avoid that kind of input? Also what is the best way to prevent spams and marketing to forms?
PS: I’ve done my research but i cant find any free plugins to do that. Wp forms has this feature but only in pro version. Any recommendations guys?

CleanTalk – it isn’t free, but it costs $12 per year, and is well worth it.
