The ban won't be removed. Sorry.
If it was not an exploit which resulted in a crashed server, I may have had a bit more leniency, crashing or otherwise making the server inaccessible to our members is a large offense and I should have never brought up the "get out of banned for $50 card", truthfully I regretted saying that as soon as it was posted, but it was too late for me to go back and edit it before you quoted it which is why I decided at the time to let it go on.
There's no real way for me to test your sincerity, so the ban will remain.
Next time, think twice. And don't think that you're safe on other servers because I share exploit fly traps with other communities.
