There is a way to bypass captchas on Pastebin, but its a pain and you would need to write a script to automate it, but here is how it goes.
Go to Pastebin and sign in with a twitter account (can be brand new, doesn't matter)
Pick a random pastebin username
now create a new paste that does not trigger the spam system (just write "hello world"), name the paste also "hello world"
publish the paste (you will not be prompted with a captcha) when its published click on "edit"
now you can edit the "hello world" paste and paste name into anything you want without triggering a captcha
If you can automate this process, you are set.
