More? I don't think so, 8 new sources were just added few weeks back. We're still waiting to see the impact of those new sources. I'll recommend advocating for an increase in the amount of smerits allocated to them (if there be a need for more smerits in circulation) instead of advocating for new sources.
It's either bad or good when there are new merit sources rather than increasing the smerit that the merit sources. New merit sources means there are new criteria. Each person have their own criteria on how they reward their smerit so new merit sources will reward smerit base on their own criteria and those who are constructive poster or those who want to contribute have a chance to be rewarded with smerit. Not all person can pass the strict criteria of a merit sources.
Merit source 1 = Strict Criteria : me ( not pass )
New Merit source = new criteria : me ( I have a chance to pass )
