Interesting speculation, but wrong all the same. The type of forum you post at (Final Fantasy) leads me to believe you have no real life friends, actually, whereas LastOCP is pretty much full of drunken, church-burning party cats with a penchant for humor and a deathwish to the anti-social.
IP addresses won't prove anything, 1. because proxies ae abundant, and 2. because we're not actually the same people. Yes, we talk about your forum on our message board; yes we've got multiple members signing up here to defend what is just and right! You can't strike down the righteous, for their will lives on far past the weeds that grow green from the graves of its roses.
Whatever your interests are, you cannot state as fact whether or not someone has friends. That goes for you too, Gaara. Oh, I'd just like to add that people such as those you have described on LOCP truly are what friends are made of

True, in that case, IP addresses could not prove much. However, what we can do is play by the rules ourselves, and warn where appropriate, because your track records are going the same way as Sar and Abel.
"what is just and right"? What, do tell, is right about posting pornographic images on a forum where children and teenagers come together to discuss a game?
The given arguments FOR bringing them back are not very convincing yet. Subsequently, that means that these members will NOT be returning. However, feel free to attempt and give compelling evidence, but, judging by what's been said so far, your attempts will be futile. I'd suggest giving up completely on the topic and moving on to a forum that will accept and approve of members such as them.
