About half of those long chains are people being unnecessarily hostile and/or talking past each other. I don't read those past a few comments; don’t like that energy. I do tag whomever is involved so I know to avoid interacting with them in most cases, but that’s about it.

Otherwise I tend to read all the comments as long as its not hopelessly dull.

The duality of comments is wild

Depends on how engaging the chain is I suppose :3 sometimes I read the first one, and I can already tell it's bullshit all the way down, sometimes there's decent content to be seen

I've never done a lone of coke so I don't know where I would stop.

A mate of mine did a line of jelly crystals once to prevent 2 damage points in a game of magic the gathering. I wouldn't do even one line of jelly crystals.
