I disagree with bringing in more redditors to this site. I think the community ambassador system is a quick way of creating a bunch of powermoderators on a system that's supposed to be designed to resist that kind of behavior and centralization.
If you hate being downvoted because of disagreement, why would you want to bring more users who default to that behavior?
I also do not believe you should have any more power or capacity in the fediverse. It's clear to me by your behavior in this thread that even basic things like being downvoted can set you off and make you decide to try to start a witch hunt.
You calling somebody out publicly is entirely to illicit a reaction from the crowd. Surely, a direct message would have been more appropriate for a disagreement over a series of downvotes?
By doing this publicly you've definitely made the situation way, way worse than it had to be.
