>>7127574The difference is that back on /jp/ something like Senzawa was off-topic for /jp/ -in specific- because it had nothing to do with Hololive or Japanese vtubers. HoloEN was already on thin ice as topical there but was close-enough on technicality and there just wasn't a better option. Here, that's not the same thing.
Past life as in prior incarnation of a vtuber as a different vtuber is generally fine unless it's very-closely tied to roommate shit aka the only reason someone would bring it up is to segue to IRL shit which is bannable. As long as it's just about prior incarnations as a vtuber and nothing else it's generally not really a big deal here. It's still considered quite rude to bring up and old iteration of a vtuber to her face on-stream however, for various reasons really but usually they shed their old model for a reason and would rather not entertain old drama bullshit around it if applicable.
