Not enough info here to draw any conclusions. Changing IP only will likely trigger a ban-evasion ban.
I’ve been using Reddit since 2008, a dozen accounts, only got banned from one subreddit ever for calling out racism (actual, not the deflated, wishy-washy kind). It’s hard to take these stories at face value.
Opposing anecdote of an error-prone system: I'd been using Reddit for 10+ years. Just one account. Hundreds of thousands of karma, mostly comments. No suspensions, subreddit-banned once from a smaller political one. No VPNs. No travel.
One morning, completely inexplicable sitewide shadowban. Took a while to figure it out, and during that time everything I'd ever written vanished like smoke from the public eye, as well as all replies. Moderators could approve my posts, only for them to become magically de-approved with no logged cause.
I finally figured out what was going on, and submitted an appeal. The appeal was "granted" (no detail)... Yet nothing changed! Then the appeals page stopped working because it falsely claimed my account was in good standing, and other tries at support-tickets went into the void.
OK, so I had an ancient account I'd used for anonymous resume feedback. Dug it up and tried asking others for advice help-related subreddits. *Bam*, same thing happened to it. The algorithm decided I was Archibald Tuttle, and there was no way to fix their typo.
It may be a "first-world problem", but especially after everything-remote COVID, the incomprehensible exile left marks. Heck, even at this exact moment, Youtube's main site won't load, and instead of finding the outage odd or amusing, I'm plagued with anxiety is that some crazed system has branded me with a scarlet-letter.
One reasons people’s experiences differ here is that IP ranges of certain countries (outside of the very mainstream west) are much faster to get banned.
