Nothing shady but you obviously understand my technological interest. vBulletin forum says: Registration denied, this forum runs an active policy of not allowing spammers. If you are not a spammer, you likely tried using a username already used for spamming, please try entering a different username. Otherwise, please contact us via the "Contact Us" page link if you believe this is in error. Any other way to register without going to a Wi-Fi cafe? TOR, UltraSurf and (free) VPN are all blocked. Maybe I can get a list of fresh public proxies not blocked yet? Or they use another technology and no chance?
