For me, it's not a matter of 10bux, but I wouldn't trust goons with my payment info. $10 means nothing to me, but privacy is everything.
It's hard to be even pseudonymous when the admins know your CC info that is linked to your real identity. A lot of people on SA are creeps who like to "dox" people because they have nothing better to do.
Someone with an SA account should make a script to scrape all old archived/paywalled threads and host them elsewhere for free. It's not that hard to use wget or curl to automatically download bulk threads.
Unrelated to paywalls, but related to SA, that site seems very similar to a lot of anime/tech/"nerd" message boards except for the fact that they pretend to be normal and not losers. At least people on *chan sites admit they're dorks. The community of SA is in denial about their social stature. How can goons can watch anime "ironically"? No one who actually dislikes anime does that... at least not to the extent that they do.
>Wow anime sucks here's a deconstruction of the last 80 full anime shows I watched in the past year! I only watched them to insult them, I swear!
