>>343>read ban messages (bots don't see them)
It probably is real people but i just have to say, bots can "read" ban messages. When you attempt to post, it redirects you to the ban message. If the system says the banned person has "read" the message, it really just means that IP has tried posting since being banned, being redirected to the ban page. It does not actually quantify if it's been "read" in a human sense, so a bot *can* "read" the ban messages.
In my experience, most of these posts are bots, like 99%. The only time it isn't a bot is when you can tell it's deliberate spam to annoy the creators, this is just imageboard spam. There are just bots that try to post to anything online, if there's a form open, they're trying to post to it. These bots have gotten eerily human-like, as people are still running these bots. This is why they tend to have "active hours", which are the same as the owner's, and it's why they need to scrape pastebin to find links (someone needs to direct the bot to the site), and bots can still fill out recaptcha, including the checkbox recaptcha. Captcha is not 100% reliable, it's realistically only like 50% reliable, it just reduces the amount of attempts cause some people don't care that their bots can't post to places with captcha.
