I think the reverse is actually the case here, just as it has been said earlier in this thread. I think it's a dearth of BTC good signature campaign rather than lack of good posters, and I also think there are more than enough good posters to go round the campaigns, but there are not just enough open slots for them, which takes them to enroll in the majority campaigns which happens to be shitty ICO campaigns; which might actually be a waste of time for them, and no compensation for their good efforts through their posts on the forum.
I agree with you on this and it's due to a user appreciating anothers posting style, which is very important, and the impression the user has created on the forum, good posters who have cemented their legacy as such(good posters)tend to always receive merits even if what's written at that particular time is just normal or not worth merits, thats why it's always important for users to create good impressions on the forum and present themselves as good/quality posters from the outset.
