parasociality will creep in at least a little bit no matter how hard you try to correct for it. nobody on here could write a complete portrait of themselves for you if they tried. you will fill in the missing details according to your perspective and invariably get it wrong
i mean, i could not write a complete portrait for my ex-spouse, whom i lived with for over 10 years, no matter how hard i tried. it's just not realistic to assume that anyone sees the complete existence of anyone else, and that's where projections come from: we fill in the gaps.
Internet people aren't real, we're all just little gremlins hiding in the magic box. Posting is the act of becoming a gremlin. Gremlinization, if you will.
This is also true of people you meet irl too. I find it a bit odd how people try to seperate online and irl relationships because of the nature of where they started rather than how well you know someone/how often you interact with someone.
the line I draw is when it crosses into speculative territory - that’s when I know I’m in too deep and need to dial back
“I wonder if s/he thinks of me- wait no bad Vee stop speculating about strangers’ thoughts”
even that can be done in a healthy-ish(?) way (e.g. yearning); it really varies
