I'm not sure, but I think that people accept weird picks more in higher ranked games.
I remember when I finally settled on a main, Rammus Top to be precise, and set off into ranked, people kept thinking I was trolling. Then again, TP+Revive would look pretty troll when combined with a jungler for a top laner.
Made it into Plat, accusation rates started diminishing. Revive got removed, changed it up for Flash+Ignite, climbed up a little higher, I stopped getting accused of trolling AT ALL (though sometimes people put into chat "no tp?", but that's the most they'll say).
The reason? imo, I think people in lower ranks only have experience against meta picks, and don't know how to play with or against weird picks, which is what makes them work and... not work. It works because the people you're up against in lane have no idea how to deal with your champ, but your team might also struggle to keep up with you.
My advice for you? If you play a weird champ, make sure it can carry the team. Otherwise, play a champ that your team knows how to play with, because some people have really low tolerance for what they think will ruin the game for them.
