Reporting of one-liners has been encouraged over the period of time. But should we report all the one-liner spams which are being made to increase the post count and receive pay for it?
For instance some of the signatures allow a maximum of 60 posts to be made in a one-week time. It's not really easier to reach 60 without spamming with senseless one-liners or being active for the whole day actually. Unless if the post contributes someway or the other to the discussion its good to leave the post without reporting. MODs probably expect such activity from us,the reporters. Some of the sections are very much inactive where those one-liner posts serve the purpose of a not-bad discussion taking place. If I were to report those posts and they were removed, there would be no discussion taking place. Hence, at such sections I leave those one-liner posters free to post what they think.
I have reported over 800-850 posts till now with a 100% accuracy but I don't report the one-liners which does say something useful in their post. Low value useless shits which are being made for the sole purpose of increasing the post count are meant to be reported for sure. Other than that, merit is an important criteria to prevent the account farming on a larger extent and they do serve the purpose now. As LoyceV said I have been reporting older posts until I saw the post of hilariousandco mentioning the reports don't serve the purpose and it's just waste of our time and MOD's time to clean the older posts.
Strangely, these posts have been marked as bad. Other high-spam users have also been cleared for similar posts.
Reporting one-liner spams are commonly marked as bad or either left unhandled. It's proably because MODs think these shits contribute to the discussion.

Not just this I have seen even high paying campaign participants seems to be making low effort posts in the 10-15th pages of a discussion. So, what to do with them?
Most of the offenders tend to stick to the low-hanging fruit type of threads and boards. These include: Trading/Bitcoin Discussion, Economics, Altcoin Discussion, etc. (you all know where)
Gambling Discussion?

One among the shittiest sections in the whole forum which can stand as a competitor to the Altcoin Discussion.
