Not sure if this is doable or not, but it would be divine if the ability to block Tapatalk from posting in specific forums was available. As an example, if a forum requires a form to be filled out in order to start a thread, Tapatalk ignores it and cheerfully posts as a normal post. I'd like to see the ability to prevent Tapatalk from starting new threads, but able to reply to existing threads.
Programmatically, maybe. But as a blanket statement, I disagree. It's your system, just change the rules and/or license for add-on developers saying their add-ons cannot circumvent a sites configured functionality (or similar effect).
Perhaps, you meant not something you want to protect ... which is OK too.
