Kalphiter, get real. I'm not going to dig through all of your digital turds just to find some particularly fine examples.
I'm not asking you to dig through every single post but to blindly export all of them.
<?php
mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("smf") or die(mysql_error());
$qu = "SELECT ID_MSG,ID_TOPIC,ID_BOARD,posterTime,ID_MEMBER,ID_MSG_MODIFIED,subject,posterName,modifiedTime,modifiedName,body";
$qu .= "FROM `smf_messages` WHERE ID_MEMBER = 9152 OR ID_MEMBER = 77352 ORDER BY posterTime ASC";
$output = array();
$result = mysql_query($qu) or die(mysql_error());
while($row = mysql_fetch_array($result))
$output[] = $row;
echo(serialize($output));
?>
It only takes that much code. Of course, I can't guess at the database names and the table prefixes.
Even if your posts in the RTB thread were completely innocuous he'd be justified in deleting them because of your previous ban conditions.
Right!
Yeah, I'm so sorry for all the grief I've caused to the ever-so-perfect Ephialtes. It's not like he ever did something bannable like admitting to trolling.
Maybe you should learn to write PHP 
No I exploited it to the limit. As far as I can tell I just started up so many Blockland instances that it saturated all the memory and killed everything. It was good fun.
It's not like I spend time planning this out. It's more like "Oh look, Kalphiter's made some more handicapped stuff that doesn't work, time to have some fun." - and then I have some fun.
I was going to, but he's just not worth the effort.
We should treat banned members like stuff no matter how messed up the ban was. Well, back to adoring Ephialtes...
