We really could use a feature where we can prevent submitting an Entry using conditional logic.
For example, I have a client who uses Machform and receives multiple SPAM entries each day. The spammer keeps changing their IP Address (VPN I assume) and so I cannot block them server-side. Alternatively, they submit using different names and email addresses for each entry, however, they do have consistent use of words/links they use within a textbox field. It would be great to have to select a particular form field (or select multiple form fields) and setup logic similar to the show/hide fields, where we can specify if a form field contains "XYZ" do NOT submit the form.
ReCaptcha v2 also doesn't appear to prevent these spam entries as well. I suspect a human is filling these entries out manually.
Another article on the MachForm Community was asking for a way to prevent certain email addresses from submitting as well, so this would also work for their case.
In the meantime, if you or anyone else has a solution to my problem, I would really appreciate some feedback as to how to resolve this.
Thanks for your time & consideration.
