These are just restrictions put on newbie accounts and not something related to TOR network.
If you value your privacy above else stick to TOR, but AFAIK every TOR IP is burdened with units of evil.
I would personally switch to VPN provider instead of TOR, it will give you sufficient privacy options (at least for my standards).
Well for is really another layer of protection you are ment to use vpn with it. I myself use a VPN and DNS. The reason is quite simple. I don't like the idea of my isp having access to what I do online. What I do is my business. You don't need people snooping around to try get you into trouble. I also use it to bypass blocked website and circumvent Hulu or Netflix. But using all that stuff here for a forum is over kill. If you must a VPN is fine. My VPN is on always. Though if you use dsn it's faster since VPN encrypts everything.
