I've noticed that I am no longer getting daily coins for sending emails or nudges.

Did I happen to miss the notice of change?

Perhaps you didn't notice the notice of the change to no change.

Yes, perhaps

I went to message last night, they wanted to charge me coins??? But not gave me any in long time, not messaged but maybe 5 people in a month, maybe 1 week since last message??? No clue, didnt message person, figure a scammer? But no point of wasting coins on a probably fake profile!!!!
