Spoiler: it isn't.

So if anyone shoots at you at any time, for any reason, it's griefing? That's what this meme is poking fun at. This is just my experience and I don't speak for everyone else's, but generally when I'm attacked and killed, or manage to fend them off they don't come back for round 2. The only time people attack is when your back is turned and for now I recommend not fishing because of the way Rockstar implemented the system. That's on Rockstar and while people take advantage of it you have to decide if the risk of being gunned down is worth it.

Being shot once isn't griefing. Same with being lassoed, while it's annoying it's always one person and when I escape I kill them as fast as possible. They don't come back. These are my experiences and unless you're actually being hunted and shot down repeatedly by a group of people or even one person it isn't griefing.
