Dump with captcha

>>8
Fuck, I'm doing this. Next time someone asks for a dumper, I'll send them to my multi-purpose dumper/bit bucket for Windows script. Now I just need to brush up on my captcha cracking skills.

>>17
Oh fuck, 4chan uses re-captcha. I haven't figured out a reliable method for this one.

I did everything but the captcha part... I can get the image but I seem to need to post stuff besides the right words.
Has anybody else done this?

You forget that this is /prog/. 2 out of 3 people on this board are lowlife shut-in troll spammers.

>>21
Did you mean: 3 out of 2 people?

>>19
No way, I did just the captcha part. You should only need to submit recaptcha_challenge_field and recaptcha_response_field.
I haven't found out how to post files with Java, though.

>>23
You can't. Java has built-in protections against this kind of tasks to prevent spammers from discrediting the serious nature of the language.

>>24
Thank you for letting me know. I'll be sure to tell the cyberpolice about this feature!

Note: if you use this, you will get banned. I'm having trouble getting all the HTTP emulation stuff right.

I don't know why I didn't think of that.

I didn't write the code, like I said at the top of that post.

I can't fix that code. Anybody else?

I just finished one based on the above code.

If you use this, you will get banned. Only 7 lines (unwrapped) need to be added. It won't be hard for an experienced programmer to find what I left out.
http://pastebin.com/p4Aqwj9i

I'm done improving it. You won't get banned for using this, as it finally perfectly emulates Firefox. There is no field validation. I deleted the old version. I'm the only one who worked on this up until now, so I'd like to see what other people can come up with.
http://pastebin.com/P3ktrVWM

Would it work better if it used the non-Javascript version of recaptcha? Turn of JS in Firefox to see that it loads http://www.google.com/recaptcha/api/noscript?k=6Ldp2bsSAAAAAAJ5uyx_lx34lJeEpTLVkP5k04qc in an iframe.
