Maybe spam is the wrong word. But I get the impression that the repetitive posting is to fill space rather than inform.
If I go down on the /r/Fedoracoin first page this is what I see :
1) People having issues with their wallet or solo mining, or blockchain explorer. This kind of stuff happens and is on 99% of the cases due to people's misunderstanding of how an altcoin wallet work, or them downloaded false version on whatever odd website
2) People offering some ideas to move on : adding Fedoracoin to coingecko, making a Gridseed giveaway, fixing a mining pool, proposing TipBot for deviant Art...
That seems to be the life of a community to me

And then again, thanks for your feedback ! Feel free to contribute any time, it's always much appreciated
Hmmm. A while ago I looked at what I thought was the reedit and saw page after page of repetitive posting about some gridstake thing or I don't remember what. Now I look and see a regular reedit. I stand corrected, I think I looked at a sub sub reedit.
Carry on.
