Do you feel is it right to keep on meriting on our God Mr. Satoshi Nakamotto's OLD posts ? But I feel, people are wasting their merits by not considering young bitcoiner's QUALITY posts.

One good example here must be (other than Satohis's post), Overview of Bitcointalk Signature-Ad Campaigns. People love to merit it.

In some perspective, I do find the people who all meriting it like they all want their name to be displayed along with some famous topics.

If it is not good, is there any way to stop this ?

Why not put some upper cap for merits for each and every post ? I mean one post may have only some certain amount of merits.

Or disabling the merit button for a post after some time period (after few weeks) will be a solution here ?
