I see. Thats good. I would also like to beat their corpses but I only know one programming language and I am not a software developer anyways :/ I don't think you will share this program with anyone since 1) Stephan lynx might find a workaround if leaked 2)You spent too much time to give it away.
I wonder what it takes to build such a thing. From my amateur logic here are the components the program should have:
1) The proxies
a)The program must be able to switch, activate and use a proxy to access the internet. How to? Most languages have http requests and proxy syntax built in. So no need to reinvent the wheel.
b1)The program must be able to automatically fetch proxies. How to? Well first we must determine our proxy source.
c)We need a source that provides proxies that are not on a ban list. How to? Well that means they should probably not be on a public list. Where to get 1000 private proxies? $$$. You mentioned you did not pay for the proxies. I do not know how but I assume you have access to things a normal person wouldn't . Clearly my budget is $0. So as of now until I find out a way to get 1000's of free private proxies this program is dead to me.
b2) Back to point b, if we buy the proxies it should be easy to import a data list and let the program read and parse it. If we are using a public website then it's probable that there is no api or data list, which means that there is no choice but to make the program scrape the data from the html (which is a whole other thing itself).
2)Der captcha.
a)If a captcha is needed to post, the program must know that and be able to intercept the captcha picture to solve it. How to know and intercept? Well that is part of sending the damn spam.
b)Solving the damn captcha with accuracy.
Intercepting it is one thing, but solving it is a whole other thing. How to? Well there are many ways to go about this.
b0) manually doing it. this is out of the question though.
b1) Paying cheap labor to do it. Again my budget is $0 so even 1 cent is out of the question
b2)Make the program solve it itself. How to? I saw you mention using a neural network. This seems like the only way to go about solving the captcha. how to make a neural network? That is a post on its own. I'm not familiar nor is my math level capable of doing this. So I can't make one, BUT I can use one. It should be a lot easier to implement an already made algorithm to fit our needs. How to? Research and studying. Again another post on its own, and also is my iq high to do this? I think with time and effort perhaps..
c)Once the captcha is solved it must be attached as some cookie or sent straight. What ever the api wants. This is part of sending the damn data though.
3) Sending(and receiving) the damn data (personally I do not know much of this so bear with me)
1) The program must be able to send the data to the website server. How to?
a) It must be able to receive the requests that the website is making(ie does it need a captcha, does it need to switch ip's). I assume it does this through accessing the api that is provided by the specific website. How to get the api? I know on sp*cechan there is one, also press f12 and see how things are done
b)Once everything is in order, the program must send the damn data. How to? Well it needs to http post for sure. I'm not to sure about this, more research is needed. It needs the right cookies as well. I'll have to look into this but I hope it is fairly straight forward since this is basic knowledge.
So this is what I've come up with. That's a lot of work. Maybe someone else can come up with a better program plan or correct my knowledge.
