<.< People don't like to read the sticky threads and post in ban appeals that does not involve them ._. Maybe add a warning box in the ban appeal section for non-staff members to agree and know about posting in the ban appeal so they may think twice before posting in a ban appeal. Also maybe have it like the warning before grave digging where you check the box before posting Not sure if this is possibly but ._.
There sort of is a thing for the grave digging. It says that this thread is over 30 days old. But it has no check box If I remember correctly
What if no one can post except tmods and up and obviously the player who made the thread. Then if the player tags another person, that person can also post.
If they can't read stickies, that's their problem. Give them some warning points and soft delete their post(s).
