yes, i have made friends and had relationships (both platonic and romantic) from online interactions. it's risky, but with time you can get to know someone pretty well. i think i was 22 when i met someone off a filesharing app, that has been 20yrs ago and i felt safe going to meet him overseas. we had a years long relationship, broke up yet still are online friends. i think actually that most of my irl frienships have come from online communities of some sort, either video games or support groups. it's easier to find someone with the same interests as me. i think human interaction is a risk whether you meet them irl first or online first, in fact I have been fukt over more by ppl i met irl first, maybe that plus more accessibility is why over the years i hide behind the keyboard more and more with time, but it is important to keep in mind that the most fukt up person you could possibly meet irl, well, they know right where to look for easy prey online, be careful.
