So far, I have not heard or seen anyone on this platform complaining of their smerit vanishing or been taken away from them. ...
Exactly and that's my perception, too. I don't know why some if not many posters here in this thread are still blabbering about sMerit decay. To my knowledge this has never happened. To those blabberers: please stop spreading unchecked rumors or false information, such spreading is a disease!
IIRC when the Merit system was announced by theymos there was a clear statement from him that there's no decay, but he could implement it. There's no point in hoarding your sMerits, maybe except when you vividly oppose the Merit system and refuse deliberately to be a part of merit points flow.
So I noticed it says unused Merit can be decayed at some point in the future - What's the point of this? Is it just to keep people from stagnating their Merit and not using it?
There is currently no decay, but if hoarding seems to become a problem, I might add it.
What do the blabberers not understand here?
... In addition to continuously adding more sources, if things could still use improvement in this regard in a couple of months, I may do something like decay old sMerit and unused source merit and randomly redistribute the decayed merit. ...
Never happened to my knowledge. It may be different with sMerits that merit sources receive monthly, but those sMerits are special anyway, as they're created out of thin air for merit sources specifically. If a merit source doesn't distribute its special sMerits given monthly, I think they'll receive less special sMerits in following months. But what do I know, I'm no merit source, I read about it somewhere in this forum.
