The previous 'bot' was active from 2017 to mid 2022, with just over 2,000 posts (and in this case, that probably means 2,000 threads) on average also 3-4 posts a day. I thought he/she got blocked and therefore stopped, but apparently that wasn't the case. Maybe you can only open 2.000 threads and after that you need a new account.
Or a new account was necessary to be able to separate data. The part of me believes that it's a robot-account, also believes the person behind it is big on data collection. And somewhere there is a gigantic dashboard where he/she presents all his/her findings on habits, experiences and opinions of DIS board members.
Besides a person, this account could also be run by an alien doing research into mankind.

Could also be the Walt Disney Company doing research to better target their potential customers.
