That happened to me about 6 times on 6 different accounts.

I have my IRL Instagram account which has people I know in real life, friends, family, etc.. then I signed up for Threads with that account, but when some people from my school installed Threads, it started recommending my account to them…

So I signed up for a new account on Web, which ended up getting banned about a day later, similar sort of message as you got there. Signed up again and again, too.. same thing.

It’s annoying, I live in the Channel Islands in the UK, so a lot of products online aren’t available here, so Instagram account signups on web didn’t work initially, I had to use a VON, which in hindsight is probably what banned me.

Made multiple accs on web with a VPN set to the USA so I could access Fediverse sharing on the acc, multiple times (idk why I kept trying), then I just gave up.

Recently I signed up for an Insta account on my iPad to see if doing it on mobile helped, and it did. I tried on that since I didn’t give the app permission to my contacts so it seemed fine, that’s still the “techy” Threads account that I use now, it’s just annoying that you need an Insta acc for it. But I don’t really use it much, my main of these Twitter alternatives is Bluesky, I use Threads a lot as a tool to hoist ppl on Bsky lol.

But yeah, they need to up their game, I think they just use AI for a ton of their mod work, hence why a lot of people have been banned lately. Luckily protocol based social networks solve this, you can spin up your own account without the friction of a company, if you wish.
