Eh, not much point arguing because it'll just get another thread locked but to answer your points:
1. Even if you didn't know what SO stood for, surely you questioned what it meant assuming you read the post?
2. They don't go to school together and they aren't classmates. I know that. Also, it could easily have meant only one of them was in class, you're just making assumptions. I'm not making any kind of desperate attempt to put anyone down, I'm commenting here on the basis I've had personal conversations with oomobi.
3. Are you referring to DeathMatch's turn, which was 2 turns after oomobi had deployed 18. In the turn oomobi deployed 18 (round 12), he held Lux City and Terres Rouges. DeathMatch held Ardennes but oomobi broke the bonus with his cash. It then looks like DeathMatch took Remich to try and get in position to break oomobi's bonuses. She was deploying 3. Then oomobi played his next turn and deployed 6, pretty much clearing up DeathMatch by taking 3 of her 8 regions. By that point the game was most likely decided as it's Round 13 and the game was over in Round 16. I think you missed that this game was trench.
At least look at the game logs in depth if you want to try and argue about them.
Edit: to add to the above, you can see oomobi gave DeathMatch advice in
Game 18002854, and I expect he has given her more tips out of game since they would obviously communicate a lot, being a couple. DeathMatch also compained about oomobi getting first turn in 3/3 games which wouldn't make sense if she intended to lose.
As for your Feudal comment, it has to be in reference to
Game 17959022 in which it was actually oomobi who bombarded a load of neutrals in the first turn, before taking them the turn after. Clearly neither of them know how to play the map and it came up in Random. It's literally the only time oomobi has played on either Feudal map. DeathMatch actually deployed first turn and didn't bombard/assault anything, at least not successfully, so your information is wrong.
I'm happy to continue providing logical explanations for every point you make until this report is dealt with if you really want to go down that road. Right now I think it's clear that oomobi and DeathMatch are just playing a game together as something to do as a couple. There is an obvious skill disparity and after DeathMatch was having zero fun losing 1v1 games over and over, so they moved onto team games. The only realistic outcome of this report is for it to be noted just on the off chance anything did happen in the future.
