is there any way to disallow users to post their Email-address into a Forum post ? I do have many members who just sign-up to make 1 Forum post at which they enter just some text and then spam it with their website-URL and their Gmail-address. Is there a way to disallow entering an Email-adress, maybe disallowing the "@" sign in the Editor or something ? Or maybe disallowing it with the same way XF is changing sware-words into **** stars ? It would be great to have this not on a usergroup-basis, but probably to disallow it for users who have less than 5 posts. The reason for this is that I do not want to have my Forum-threads cluttered with "Gmail addresses" and guests just getting in touch with my members via those "Gmail-addresses" posted, but to have new users sign-up and get in touch with my existing members via Private-Conversation. Appreciate your help in how to achieve this !
