There's no hard rules, but generally we see it as abusing the system if, for example, large, well researched blogs are being done frequently. This is generally a sign of AI generation, plagiarism or something else, so more investigation is needed and cautious voting.

I think if they are quick blogs about progress we may give them a small vote, or pick and choose - short-form is quite a new phenomenon in our community, I think. More discussion needed!
