From most priority to least priority:
1. To prevent me from looking like a hypocrite in the NG Guide
2. To get rid of the administration (ban) button so that opinionated Malachy can't [ab]use it anymore
3. To hide my ban history from the BBS moderators
4. To wipe out my entire existence on the shitty forums
5. To free up server space, and the loss of server space due to the blank posts will be compensated by the deletion of the spam I have posted on the BBS, along with my unchangeable refusal to make more posts on the BBS
6. To prevent looking like an asshole and a statwhore
7. To destroy some of the threads on the BBS
8. To fuck up some post whores' post counts that they masturbate to
9. To never see the name "SuperMarioBrosS" in yellow on the forums again
10. To get rid of the Sonic fanboyism I left behind
11. To make the SuperMarioBrosS account invincible from the BBS moderators
12. To divide Malachy's advice by -1; instead of posting more to the BBS, mind as well do the opposite and destroy the existing ones.
13. To glare at that big fat 0 next to my BBS post count, and have a smile of satisfaction that my BBS problems with the BBS users have mostly (but not fully) ended on the BBS. The one problem that has not ended (and may never end) is the one with Malachy, who decided to go as far as to tricking Wade into destroying my 2,200 news posts, thus ultimately destroying my Newgrounds Guide and months of hard work. I would have covered the entire fucking flash portal and a little bit of the audio portal by now if that jackass kept his selfish ass where it belongs: in the shitty BBS. Instead of digging his nose into a place he doesn't belong in.
Thank you Wade for deleting all my BBS posts. Now in a few years I may get this account's post history destroyed as well, thus ultimately protecting my sorry ass from the mods.

You sir, are a Newgrounds paranoid
Just say that you felt like doing it

TL;DR, what Spaintendo just said.
FYI I'm not paranoid of the portals or user pages. Just the BBS.
