⭐ Merited by Who is John Galt? (1)
I also see nothing wrong with signature campaigns, why not take advantage of the additional opportunity to get more satoshi. But this also requires a separate time, so I'll deal with it a little later. 
You're right, there's nothing wrong with signature campaigns, it's an extra incentive to be here and discuss Bitcoin with strangers. If there were no signature campaigns a lot of users will not be as active as they are on the forum, it will just be a recreational forum to chat on when bored or when we have a question or are looking to learn something new.It's only a problem when users spam because of it. Churning out redundant posts on all the accounts in their farm to meet the campaign requirements.
but it looks like that there's no system in meriting. You never know for sure what others will like. It seems to me that you just need to take it easier: it's nice when you are noticed, but if no one notices... well, that's okay too! 
There are personal whims but majority of the time quality posts is universal and can be identified by anyone. The fact that a post isn't merited does not mean other users did not find it to be a quality one, but it could be they did not have smerits at the time of reading it.Just do you and put some effort into your discussions and you will get merits eventually.
