Every game I won was either a resign or an opponent time-out

So is this proof of my total dominance over these lower beings or are they just too embarrassed to admit defeat by hitting that resign button?

They all just let their timer run out.

Is this good/bad/no problem?

Babe you've only played 15 games. 500 ELO players couldn't dominate a chinchilla, and your win rate is nothing special for that many games- check in again after 200 games.

At all levels it can feel embarrassing to resign, and actually the advice usually given by strong players is to never resign at lower levels even if you're down loads of material, since there is a good chance that the opponent will stalemate or simply not know how to checkmate. You can report people who stall out the rest of their games instead of playing on or resigning, since they shouldn't be doing that.

Interesting, I don't feel it embarrassing to resign, but yeah, at 500, you shouldn't be resigning

I definitely do feel embarrassed to resign when I didn't feel like they actually played well. It's more being upset with myself, but I'd still call embarassment

Hmmm, I see what you mean.
Guess I'm too used to myself making stupid blunders to care all that much 🤣
