Why they're in hurry to get ranked?
1. Join in signature campaigns ( The higher the rank the higher earning you would get)
2. Making yourself a high rank looked a bit trustable which means scammers do make use of it
Things that i do saw on why people are really on a hurry on ranking up.
Maybe these are the reasons or maybe it's just few of the many reasons (only those who do that knows). But i think the merit system should really be controlled like introducing a new rule which will only allow higher members to merit maybe onece or twice in a week or month. That way, merits won't be given anyhow
