Question about proxies for a newbie

Hi

I've never worked with proxies before. I'm keen on buying twidium accounter as the trial is doing exactly what I need. However, in twidium accounter, it asks for a username and password to be inputted as well. I was using a trial of a tool called proxy multiplier which finds you proxies to use, and it only gave me ip addresses and no usernames or passwords.

My question is:

1) when one buys proxies, do they come with usernames and passwords that I'll be able to input into twidium accounter?
2) Are free proxies a bad idea to use, if I am trying to automatically tweet people?
3) Can anyone suggest what kind of proxies I should be getting for the use of twitter bots that will automatically send mentions to people. I am very short on cash so the cheapest solution would be appreciated

Thanks alot

Proxies are of two types...Public and Priivate Proxies

Public Proxies are died soon...
Private proxies are working long times...If you use any Automated softwaree to create backlinks or account creation...Just use Private proxies to beat these things.
I think buyproxies gives good and fast proxies with username and password

to summarize dont use public proxies for account
they will already be on multiple spam lists such as google spamhouse ect
there just not worth the time, stick with private/virgin/ proxies

lots of proxy service use Username/Password authentication,check this page

1. No, proxies do not always come with usernames and passwords, but they can, if they are configured that way.

2. Free proxies can be just as efficient as bought proxies, what's more important is what kind they are, and how often are they used. Public proxies tend to be used more often, and are thus slower.

3. If you're just starting out, I would recommend free proxies. There are methods that you can used to find these, not to mention websites that offer them like HideMyAss and others... If you want no fuss, and don't want to worry about efficiency, perhaps buying your proxies would be a better solution.
