Probably not. I have divulged some personal info on here, but not enough to narrow it down to a specific individual. My OPSEC here is sufficient but probably could be a bit better.
There are almost no breadcrumbs except the fact that I went by this username on Reddit, and I advertised my main YouTube channel on here years ago, but even if you went down breadcrumbs from said YouTube channel, even that doesn't lead to any of my personal info. As far as personal info online goes, I am a ghost and I play whack-a-mole with data broker sites monthly, so there's no information about me nor anyone in my family readily available, unless someone got lucky, had my info already, and gathered OSINT about me before I could get to it.
Only IRLs know about me, myself being behind said YouTube channel, and everything I have online that isn't work/school/personal related is created under a fake name with fake name email addresses, so If I got doxxed at all, I can very much narrow it down to who did it, besides if the feds came over again, because I don't use a VPN, and they are able to get real names and addresses through IPs just by contacting your ISP.
