LOL, my computer sometimes has a problem when it comes across a font its not familiar with. It'll give me a code, that looks something like the game codes.
Do you mean something like this פ×"ס×פ
That's not your computer, AG just doesn't have a very wide character support.
Guys, we allow those kinds of comments for games which allow you to see the "code" for a game level or song or whatever. Those are not spam and will be ignored by the admin team if they get flagged.
If comments have symbols like master656 listed, we may or may not treat those as spam, depending on what else is in the message.
If a message is entire non-English, or entirely made up of symbols like it was written in a language that doesn't use an A-Z letter system, please, by all means, flag those comments.
Please, also flag ASCII art. That doesn't belong in game comments.
