I've got to find out that there are some profiles that have received whole lots of merits but some of those profiles don't circulate their sendable merits to others profiles thereby allowing the sendable merits to decay and become worthless.
How did you check it? if you only check by clicking their merit history, it's not accurate because the forum only show last 120 days activity. Moreover it's the user's right whether he want to spend his sMerit or not, there's no obligation sMerit must be spend.
It is the user's right quite alright but it doesn't make a sense as there's no logical deduction in deciding to hold on to such right. Before a user got an S'merit some other user merited his post he/she find worth meriting and assuming all forum users walk with such mentality of hoarding S'merits how would you have gotten any S'merit not to then talk of hoarding it.
For a user deciding not to spend his S'merits on a post at all in the forum is indirectly creating the impression that such user don't see any post worth of quality that deserves meriting of all the thousands of posts found daily in the forum and a decay is much satisfying. But the question arise, does S'merit actually disappear/decay? I'll love to get a feedback from someone that had experienced it.
