I have an idea for a plugin that everyone is going to like. To bad I cannot write it myself. After running 3 forums and now my first blog. I often wondered what would be a good way to get rid of a pesky use-member who constantly goes around you blocks to get back in and post again? Using proxies etc...
Then I came up with an idea. Why get rid of them if they will just come back because we pose a challenge to them by banning them? Why not make a plugin that makes their posts invisible to everyone else except that person? In others words, he sees his own posts as if nothing is wrong, yet no one else can. So they says whatever they like, bad or good, and bugs no one because it's invisible.
So they carry on like they are debating or starting fights, or cursing and no one responds. So wanting to be noticed and heard, they feel totally ignored and leave. Or post all they want and who cares? And the joke ends up on them.
So if blocking does not work, let them post invisible posts. And bugging the moderators with this problem person is solved.
