No offense sir but I think that would be a very bad idea. I just want to emphasize that this forum is designed for all
crypto enthusiasts not for the bots. Also, the essence of this forum is not only in order to earn from signature/bounty campaigns but for us, humans, to have some knowledge and keeping an update on the latest hapoenings in crypto world. If the only reason why you suggest this is just to earn with less effort and less time exerted (in short, earning passively) during campaigns then much better if you will do mining or run a business because that will be more worth of your time for sure.
I am thinking that even a not really good one it could be better than many posters in the Alts section
It already came from your own words that it is not really a good idea. To give you a glimpse on what will happen if bots will be allowed in the forum, here's example
http://example=https://bitcointalk.org/index.php?topic=2838860.0 (Note: there is no concrete conclusion about this, maybe a bot or maybe not. Depends on what you believe in)
