My site also fluctuates during the school year -- from 6-8K per week during school year to 5K during summer. I assume it's students doing research.
However my site is not capped. I have a lot of natural links coming in which may be where the difference lies. My main focus has always been to provide info that people are searching for -- tips, tutorials, scams warnings, etc. which brings in lots of natural links.
I'm wondering if the sites that are capped are providing data that people want to link to (natural links) or are they only promoting their products, services, etc. and having to gather links?
