Yeah, I have IG (and I had a twitter account as a teenager, but I kept it for a few years only), but I don't spend a lot of time on it.
There was a time when it was a public account and I had to deal w/ disgusting guys who sexually harassed me, or friends of friends who hit on me, so now I'm bein super cautious abt who can access it. Wouldn't say it rly affected my life, it was "only" the internet and I went through much worse things when it comes to sexual harassment. All I can say is you should always be super careful, on the internet and especially irl.
