What do you think about anonymous proxies? Can those be a security threat?

Proxies are a concern for every site, but as a webmaster, there isn't very much you can do. They look like any other internet connection, unless specifically announcing themselves (via headers) as a proxy.

Ok, just wondering that is there any proxies that should be blocked in the IP-level?

It is a never-ending battle to keep up.

Go ahead and block those proxies if you want. They may be malicious actions coming from them or just innocent users. It really depends on you and how much risk your site can bear. For me, none of my site's are that sensitive to worry.

I had earlier this in my .htaccess to block proxies, but it also blocked others like some hospitals and govermental work places so I removed it:

RewriteEngine On

RewriteCond %{HTTP:VIA} !^$ [OR]
RewriteCond %{HTTP:FORWARDED} !^$ [OR]
RewriteCond %{HTTP:USERAGENT_VIA} !^$ [OR]
RewriteCond %{HTTP:X_FORWARDED_FOR} !^$ [OR]
RewriteCond %{HTTP:PROXY_CONNECTION} !^$ [OR]
RewriteCond %{HTTP:XROXY_CONNECTION} !^$ [OR]
RewriteCond %{HTTP:HTTP_PC_REMOTE_ADDR} !^$ [OR]
RewriteCond %{HTTP:HTTP_CLIENT_IP} !^$
RewriteRule .* - [F]
