I got into an argument in the main Technology community a couple weeks or so back and while I admit that it got too heated so that both of us broke the “be excellent to each other” rule, I still feel that an immediate 3-day ban with no warning or notification (I had to check the modlog to find out why I suddenly couldn’t comment there) in a group where I’d never broken the rules before was ridiculous.
Didn’t help any that the mod almost immediately unbanned the other guy who had been equally unexcellent during the exchange and initially got the same ban and left mine in place…
