It will only download what is included in the feed. Most feeds have the first x characters, which could be anything from 50 upwards. I've not seen any with less than 50 characters, but it would be possible.

Theres only so much that you can do with an RSS feed and posting it on the forums, so while I haven't seen the latest version of Articlebot, I can't imagine that it can be that different really.
Also, using stock vB functions where possible makes it a lot easier for upgrading and support if a fault happens.
