if a mod says it is not trusted, is it "ok" to still use it?
Sure. It just means that (worst case) the mod could be rigged or otherwise unfair. Also higher odds of bugs etc. (so maybe you can't commit and will get booted)
with coins, on the coin leaderboard, does it count the coins you "won back" from yourself? cause technically, when you someone (or u) joins an open game you're coins go away until the game ends. so does it count the coins you win from urself on winning coins for leaderboard?
Yes, the coins you win from a game counts. So in a 1 coin game, you win 2 coins.
why do some lotto tourney games give u like 8000 points when regular games (strat mme, 2v2 FE, biomes, etc... ) give u like 7000?https://www.warzone.com/wiki/Points
