No ads and no booster

If you purchased anything with real money, say goodbye to boosters. In a while, a moderator will tell you the poem about 'ads are a feature that is still getting tested and it will come back'. If you didn't buy anything, it will come back actually. Hope you are lucky enough you didn't buy anything. Sorry.

Some features (like ads) do come and go at random times. Features are a bit random in general. But there does seem to be a rumor that ingame purchases remove this feature permanently.
