Some rated games aren't changing rating

That's normal for bot accounts if they repeat opening and opponent

Is it supposed to be only when both opening and opponent are the same or also if just the opening is the same?

Iirv both

Yesterday finished game verse Panda765. Rating didn't increase to 1975.

Up until last month, I supported Lichess financially. That ended because support doesn't reply to valid concerns (like why my win didn't increase my score yesterday). If one doesn't see any reward for effort, & support doesn't fix issues like this, why play on this website?

Your rating did update

@wicked sigil the rating on the next game was started before your prior game finished, so it has the old rating. But your current reading is 1975. Thanks for your prior support

How many plies counts as repeating opening.

The antifarming logic I found suggests 20 plies. These come nowhere close to that.

I'm surprised that bot is allowed to play rated games at all...

Is there a specific rule I should be aware of?
Or preference?
