Yes, 5 - 10 submissions per user are enough.
No, any user should be able to dominate the list alone and have the monopoly.
Paid submissions aren't a long term regardless. And the nice thing about a free market is the market regulates its self. The submissions only continue when there's a profit being made. When a profit is no longer being made the submissions stop.
The difference is this guy found a way to make profit with the amount of submissions being sent in today. Can't blame him. If you can make a return why not keep it up, and even start submitting more?
Submit new proxies -
Very good observations made by Keldorn.
That can only happen so long until people run out of money.
It does seem sort of silly to assume that all of those people are losing money and that they continue the same money-losing behavior week after week.
I agree TF should't accept .co.cc domains hehe
Now to do what I find insane in the US president is having all tires bought in the US that cam from China will have a higher tax rate then those that were made in the US.
So instead of saying block or ban the co.cc domains maybe say hit them with a slightly higher submission fee. Even so the submissions of them would not slow as they are making money on it and users are getting used to proxies having a wide variety of extensions.
I only presently changed my site to accept them as someone explained it was poor business sense not to accept them. In the end the users want working proxies so if a co.cc works for what they need then everyone made out the user and the owners.
Enough of my dribble just my run on thoughts of the topic.
Twitter has kind of a monopoly though, except for a few clones but there isn't a site that's the same like Twitter
It's not like it is hard for you to jump into the monopoly.. so there really is no point in complaining.
