I don't think this forum needs registration date elitism. People already have enough excuses to insult and fallaciously disregard other people's arguments. We don't need people to think that the points of idiots are more valid or truthful just because they've been her awhile and we don't need people to think that new people are idiots and their opinions shouldn't be acknowledged just because they're new.
Jesus. This forum is scaring me. Usually, I'm the wackadoo on any particular forum, but lately I've been reluctant to post because I've been out-crazied. You know that you're insane when you see a hobo with crap-ridden pants backing away from you slowly.
Also, anyone who is ragging about free speech and censorship needs to understand that those principles don't apply in internet forums any more than they apply to me if I take a sharpie to your apartment walls. Those are governmental concepts. This forum is not run by the government. You have no right to free speech here only so much as they can't censor based on a user's characteristic of being part of a special group (E.G., you can censor me for being gay if I'm posting about bitcoins within guidelines that apply to non-gays).
This isn't even specifically about moderating offensiveness or spam, but relevance. Deleting someone's thread that says "Sell sell sell" is no different, in terms of free speech, from deleting a thread I might make featuring the entirety of the amino acid sequences for trypsin family proteases compared between various key animals so we might talk about concerted evolution with nary a mention of bitcoins.
