I think that you guys should allow the /plotme deny command or /plotme ban command. I know this is in the plotme plugin, because I have seen it on other servers. For example, if someone kept splashing splash potions of speed on you non-stop or got in the way of the block you were trying to place down (*ahem* jeremycraft14 *ahem ahem*). So, yeah! Just a suggestion! It would be very nice if you added this!
Many people are requesting this command. I agree with it but my only hesitation is that it would cause more drama then there already is. I think it would be a good idea though.
apparently there is something wrong with /p deny and I think someone said it interferes with world-guard or something. And this feature has been requested a lot but unfortunately it cannot be enabled..
