Heh heh. We would see more merit-buying and trading than we would post improvement. I'm 100% sure of that. Shitposters try to "improve" their posts by making them longer, and the results are usually not pretty--take a look at the Meta section after the 1-merit requirement went into effect, and you'll see what I mean.
If you're a shitposter, you don't just magically come up with something interesting to say or with improved language and writing skills. What's more likely is that we'd see more plagiarism if that merit requirement were boosted to 10, in addition to people trying to buy those 10 merits.
Well, we are both here speculation about what could happen because we don’t know for certain. I’m sure that some people would make an effort, but my point is not so much about people’s behaviour as about mathematical certainty: merit-buying and trading is more difficult with a 10-merit requirement than with a 1 merit requirement.
As for what would happen with shitposters trying to improve their post by just making their shitposts longer, I think this would be the case but not much worse than it is now. When the merit system was implemented,
shitposters started doing that.
Then, when the 1 merit requirement was introduced, some more started doing that. It could be seen on meta but I didn’t see a huge difference overall. However, there were some that realized that could make the effort to write some good posts to get one merit, although they were a minority, of course, but we have a guy on this same thread:
A few weeks ago when I found out I needed one single merit to publish images I was almost depressed....
Since then, 3 weeks have passed and 48 merits have appeared on my account, whether it was simple - no, but whether it was very difficult - either not.
It was enough to think a little bit and put some work and effort.
And I've seen others sharing a similar experience.
Shitposters are always going to try to cheat but I think the 10 merit requirement has to be implemented not so much because of the possible effects, as because it sends the message that if you want to get paid to post, you have to make efforts and earn merit. That’s what the merit system is about, isn’t it?
