Highscores are invisible

For some time now, you can't see my highscores in the maps. Not even in the Daily Challenge my friends can see my score. Now I did some research and saw that there seems to be something like an Invisible Ban and I don't know why I could have one. I tried a Chrome extension a long time ago that was considered a cheat, but I deleted it right after. If this is the reason why I have such a ban, I would like to apologize and assure that it will not happen again.
