No shortage of IP addresses

I doubt that they do not count failed login attempts across servers.. Otherwise bruteforcing would be too easy/possible.

How about project euler?

What is Project Euler?
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.


Who are the problems aimed at?
The intended audience include students for whom the basic curriculum is not feeding their hunger to learn, adults whose background was not primarily mathematics but had an interest in things mathematical, and professionals who want to keep their problem solving and mathematics on the cutting edge.


Can anyone solve the problems?
The problems range in difficulty and for many the experience is inductive chain learning. That is, by solving one problem it will expose you to a new concept that allows you to undertake a previously inaccessible problem. So the determined participant will slowly but surely work his/her way through every problem.

Surprised nobody mentioned vezzy's guide to linux distributions: https://evilzone.org/operating-system/an-informal-guide-to-linux-distributions-for-the-unwashed-hacker/
It's a nice writeup of the most popular linux distros

First, use the [ c o d e ] and [ / c o d e ] BBcode tags to make your code more readable.

Secondly, you didn't proxy the requests through tor. You just started the service, but didn't connect to it.
Also, don't use os.system if you don't have to. There are better ways to do this:

As you're already using python, I'd suggest the stem library (https://stem.torproject.org/)
It's a python controller library for tor, so it allows, for example, changing the identity. That way you don't have to restart the tor service everytime to get a new identity. Furthermore it makes your code more portable (should work on windows too).
FYI, the requests library doesn't support SOCKS proxies (wich tor is using), so you'll have to look for another http library that does support SOCKS proxies. httplib2 supports these kind of proxies if you have the pysocks/socksipy library installed (pysocks is the more recent fork, socksipy isn't actively developed anymore).

As for the code in general, using a for-loop would make it look cleaner (matter of taste). Assinging the content of the yourtube url to the variable "res" is unneccessary, as you do not use the variable later on.

You should read up on SSL first, because you obviosly don't know much...

hello folks, someone are using some version of the reliable UDP? Since currently there is no standard, as it was thought to make it happen and with what restrictions apply? 

There's a fairly old experimental standard:
https://tools.ietf.org/html/rfc908
https://tools.ietf.org/html/rfc1151

As well as a slightly more recent draft:
https://tools.ietf.org/html/draft-ietf-sigtran-reliable-udp-00

And there's Lossless UDP from the TOX project:
https://github.com/irungentoo/toxcore/wiki/Lossless-UDP
https://wiki.tox.im/index.php/Lossless_UDP

Also, I forgot to mention that if you enclose your code with the [ c o d e ] and [ / c o d e ]  tags it gets formatted to be easier to read. You can also specify a language for syntax-highlighting like this (e.g. python): [ c o d e = p y t h o n ]

You'd have to block all the throw-away-email services like Guerrilla Mail, and there are tons of them out there...

I'd also suggest to go at least for a CAPTCHA system, as it makes flooding spam way harder.
