Lets discuss about about putting the word proxy in your topsites domain. Do you think this is good? When people submit to your topsite and link back they end up filling there html with word proxy and getting it blocked faster.
do you submit to these sites? Or only submit to ones without the word proxy in the domain?
Peronally I don't think its good and I don't submit to these topsites.

I've done some experimenting. I can safely put the word proxy a few times, in the html and the site won't get rated as proxy avoidance. But I if put the word more then once then it gets rated as proxy avoidance and it will says something like "contained phrase "proxy & proxi, web proxy proxy we"
(example from lightspeed)

Okay well next if you find one that doesn't have the word proxy in the domain, the owner of the topsite might still be an ass and reject your site if you do'nt put proxy in the anchor text though. Not something I do either. I think the link on my site is your advertisement strictly for Click threws to your topsite. If you want to do SEO, do it like everyone else and submit to link directories or something.

I'm planning to have another url pointing to my listing site so that can be safely use on proxy sites, but doing this will affect my linkback and will not getting my main domain PR at all.

Still looking for a best way.

Other than that, what proxy owner can do is to use a php include and call an external page. That external page should be encrypted so that spider wont see it.

get me?

Hmmmn something to think about ..... however I reject listing on anchor text .....
only the linkback should be present!

Many topsites use a spider (automated) to check for the backlink if you encrypt it, the link won't be there. Well I know Tech-faq and similiar sites on the same script do use a spider to check, as with Proxy.org he uses spider once and awhile so you link is not found your site gets dropped.
Btw your site is down right now as I write this, has been down all day yesterday and is now 3am now.

My site is down? Didn't know that..
How is it now?

I think I have to keep it separated from my proxy server.

Its on now but going really slow. Its like hanging, like the bandwidth is choked or server is too busy.
If you were move it, you can cheap shared account at http://www.T35.com, I used to have an account there. Alex melen is a great guy, $4.99/month 10 gigs of bandwidth more then enough for a topsite.

I've made my research and bought a hosting package from HostV. You can find them in WHT.
I bought a VPS from them so I guess it will be used for hosting only 2 sites of mine separated from my proxy server.
