Anyone here an experienced Reddit scraper?

I am going to do a big project there scraping posts for word usage, and looking for correlation between seemingly unrelated subreddits. Does anyone here have any wise information about scraping there? I anticipate this project is going to be a few months long if not a year.

My main concern is avoiding detection. Of course I am going to use dummy accounts, but what is the best practice as far as bandwidth limiting. I don't actually need to crawl the whole site, so I don't need to crawl fast, I just need to do it efficiently.

I should make a new post on this... anyone have any experience capturing sites (or subredddits) with HTtrack and then scraping your copy multiple times?
