It's not a bot, it's just abnormal posting behavior from a human with a motive unknown to us. It's also not that he isn't reading anything, he reads the post that he replies to, but doesn't think much or write much in his response, he reads the post quickly, makes a quick response within 2 minutes or so, and moves to the next topic immediately and does the same again. So he isn't using a bot, most probably, but what he is doing isn't normal.
I agree, that's not normal behavior from someone who is interested in discussing in one thread or another, there should be a break for him to think more critically so that his posts are much more meaningful. But I call it a unique habit pattern regardless of the motive, it is also because the system allows users who have high activity points to reduce the waiting time between posts.
Someone else including you or me can also post what we think is of value with the same behavior, in fact you can do it every few seconds in 4 to 6 or even more different threads. The condition is that you have to prepare your reply first on each thread, then you post them sequentially with an interval of just a few seconds. You can do the same thing when you want to send a report to a moderator or also when you send merit to dozens of different users. This method saves you time, but when it comes to posting, then I admit this is not a good behavior to maintain.
Implementing a system that would restrict every member from posting only because of a single person's behavior wouldn't be fair. Maybe there should be a privilege given to moderators for implementing such restrictions on specific users who are being reported a lot for spamming and post-bursting. A moderator should be able to put a timer on their account so that they can only post once within a specified timeframe such as 10 minutes or so.
Spam and low-quality posts with relatively short time lags are classic problems on this forum. You can always report it to a moderator and hope that the user you reported changes their habits. If his behavior does not change, it is possible for him to get a temporary or permanent ban.
