You should really add a few more words since I have no clue what you mean. You said you kept posting with the hope you would receive that upvote sooner or later..well it'was a lot later.

It's a fact that people do a lot for empty promises. Look at loteries, ponzi schemes, contests where you receive 100% from the host who has 0 and there are many more "sales" tricks.

I assume you read the news that the boosting votes no longer will belong to a community? Not that it changes anything for you. Let's see if there will arise more communities with a topic like in the old days.
Goodnight!
