I don't really think that deleting some BBS posts can get rid of fanboyism.
Also, if you had BBS posts, you could show viewers of the guide that you learned over time and know what the BBS is like, instead of ranting about how it is a piece of crap.

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