Example: 1. I was just playing a player named "Elena" with 2500+ ELO, and was dominating rallies quite easily, all of a sudden they started using this glitching/cheating in-between shot where you return the ball with a sort of in-between swing (don't know exactly how to explain, because it's not a legitimate shot) and all of a sudden the ball hits the back of the line every time. It was not a legitimate shot, and pretty sure it's a glitch that shouldn't be used, but every time they were in trouble all of a sudden every return started hitting the back of the line, during every rally on their serve down break points they did this shot even while running at full speed = obviously they won most of those points as it's impossible to defend. Is there a term for this glitching shot? And I know it's true because they only used it during the "big points".
2. A LOT of "sudden lag", conveniently when it's about to be the end of the match. Somehow this lag just delays the match to a literal standstill, and it ends up being that they "retire" and probably lose less ELO than they would have with a legitimate loss, or maybe they just don't want to legitimately lose. For some reason, this also makes ME lose ELO, which is why even if I win sometimes with this sudden "lag" somehow my ELO goes from like 2280 to 2260, despite winning! It shows like +15 meanwhile I am somehow losing points.
3. Random bad reputation. My reputation went from very good, like +40, to a -30 in one week span of beating good players despite doing absolutely nothing wrong.
4. Unrelated but they are all lefties too. Seriously, I play a right-handed player about 1 out of 5 times, it's ridiculous. Of course it has natural advantage with the stupid topspin, this is why Nadal is a meme too. But that has nothing to do with the game

I thought a game with a smaller community would be a nicer place, but the insults, cheating, glitching as soon as I start playing the elites is very funny and disappointing to me.
