Our client's form is being spammed by russian bots and they would like to prevent this type of spam by preventing users from either entering, or properly submitting forms which contain cyrillic text

Of course, we can probably prevent users from submitting the form depending on the character set that they use.

Our process

Here's what we did

Progress update

I decided to go with back-end php validation instead of jquery since bots can just ignore jquery.

Ultimately I wrote the code snippet with a combination of PHP and Jquery. I then created a dummy page and added a new form to it in order to test the new submission criteria.

Our Goals
  • Use either JQuery, PHP, or both to prevent users from entering cyrillic text into form input fields

Awesome! I'm really happy to have this done since it should cut down on the amount of form spam that we've been seeing recently. Thanks!
