Effort != high quality. A high quality post might only be a couple of words long, if it directly answers a technical question or problem, for example. There are also plenty of threads dotted about various boards, but particularly in Beginner's and Help, which I'm sure the OP spent several hours composing, but if the information contained within them is wrong, inaccurate, simply copied from other sources/other posts, not relevant to crypto, not useful, and so forth, then I don't think that's of particularly high quality.
Effort != Length
To concisely answer a question without using too much jargon, and making it complicated is effort. You're making an effort to make that post concise, and straight to the point. Effort just means that they've made an attempt to answer the question or contribute to the discussion. This is incredibly difficult to avoid when discussing the technical aspects of cryptocurrencies.
If its completely factually wrong, and just gibberish yeah I would agree. However, if it has some aspects which are factually incorrect, but overall has good content then I personally wouldn't write that post off. I've merited several posts which have been factually incorrect. This is especially true when it comes to discussing the technical aspects of Bitcoin it is very easy to use a different word which completely changes the meaning of the sentence, but overall the post is correct or providing a different insight.
It's worth mentioning that there's been several users with basic understanding of Bitcoin, and the Blockchain and are putting in the effort to learn about Bitcoin, but not quite understanding it. However, they're putting in effort to learn, and in return are providing high quality content even if its not quite factually correct.
We all have different merit awarding criteria, and that's the good thing about the system.
