I am not very sure about that rule. I have applied but have found that I myself, despite earning merits at a rate of almost double my activity, have sometimes gone a week without receiving a single merit. If he accepts me I will bring it up for discussion. I guess it would be better to change the requirement to get 4 merits in a month
I think this rule is to enforce participants make more and higher quality posts. However, you made a point that a good post does not always receive merit.
More important, many people got merit by exchanging in their local farms or local communities. This rule can be abused by merit exchange to stay in the campaign.
Anyway, think positively about it as it can increase general post quality, I consider it is a good initiative.
In general I agree with what you say, but if I myself, who I think I am the second best in terms of merit/activity ratio of all those who have applied so far (the second after you), have had weeks of not earning a single merit, to earn 50 merits in the next one. I would not see much sense to have to kick someone like me out of the campaign, and most likely those who are worse than me, he will have to be changing them every week.
What I understand that it can incentivize is the merit exchange, as you say, or the merit with alts in order not to be expelled from the campaign.
Only 5 posts are required in Gambling and the rest 20 posts can be non-gambling.
Yes, but usually in this kind of campaigns, there are people who write 80% of posts in the gambling section or more, even if the requirement is lower. Those will have a harder time to earn merits.
Btw: I gave your weekly merit, so you are not going to be kicked out. Lol. As I am sure you will be accepted.
