The number of merits distributed by merit source monthly continues to drop, if you check the DdmrDdmr merit dashboard which is a clear fact that most merit source don't even use much of their allocated Merits because of low quality post and issues like this.
If merit sources are unable to empty their monthly allocation due not enough quality posts, isn't that another argument for reducing the amount of merit that is generated each month?
Last time theymos did a big merit readjustment was ~July 2021 and since then number of posts dropped by 40-50% while amount of merit shared didn't drop that much, which then brings us to these kind of situations.
Perhaps some of the merit source are inactive or not as active as they used to and that could be another argument for adding another set of merit source to replace those inactive ones. There's always two side to look at for every situation.
