It goes both ways.
Only Diamond 4ish, but whenever I've lost games to bronze/silver players or do not perform as well with those sorts of players on my team, I'm met with a constant barrage of comments like "how much did you pay for that elo job?" and "how'd you get diamond? you're playing worse than I am, yet I'm stuck in bronze 3 wtf". Eventually just learned to mute/ignore these players as there's no reasoning with people who can't accept that bad games happen sometimes and just because I'm a higher rating than they are, doesn't mean I always play perfectly.
