My understanding of local rules is that only the topic starter aka OP may create them & they are only enforceable to the extent of what is verifiable & possible for forum staff to do on SMF. The violations I cited are verifiable because replies to auction topics are non-editable, and it's possible for forum staff to lifetime-ban a username.
There's no way forum staff can verify whether someone has paid you $1000. And as you are not the OP, I am, your "rules" in my topic are null & void. Additionally, if you had substituted "or be citizens' arrested in real life by forum staff" for "or get banned", that would not be possible, as forum staff would not be able to make a citizens' arrest in real life on SMF.
