I made a spambot for 4chon as can be seen here: https://www.4chon.me/meta/res/3423.htmlhttps://www.4chon.me/r9k/res/9618.html
It was trivially easy. I used a python library called selenium. Fortunately for ol' redditcucky the robot seems to have deterred me from shitting up his boring blog thread without effort. I can spam threads on the boards other than /r9k/ all I want, but the problem is my bot desynches either due to my internet or my hardware. This is why it would type out a sentence more than once when it wasn't supposed to in that /meta/ thread. I'm not actually sure, but It's pretty slow, so I don't think it would damage the site. It takes more than 5 minutes to make 100 posts. I was pretty confident that I could PWN /r9k/ threads, but my bot kept getting muted as desynches kept preventing it from typing something original. If I wanted to try again it wouldn't be difficult to just have the spambot write random gibberish, so that the chances of tripping the originality filter were minimal. It would also bypass the word count as an obstacle, which is another thing I considered a problem. It is fairly unlikely that I will use it again, as my computer got quite loud after a running it for a bit.
It does go to show how vulnerable this site is though. It's got no flood detection, no captcha, and no big list of banned proxies, which is GOOD! There is a steeper learning curve for pulling this off on 4cuck or 8cunt.
