Thanks for the article. I'll throw in my two cents on one point:

"The project stops new sign-ups for a period greater than 5 consecutive days"

Just yesterday I tried adding YAFU from the BOINC manager and discovered they are not accepting new accounts. This project is currently whitelisted. I want to add that to this discussion because I am not sure why they are not accepting new accounts; if there is an essential reason for doing so, that must be factored into drafting whitelist requirements.

[also, I want to make sure it is in fact the case that they are not accepting new accounts, and not some bug with my local BOINC version or otherwise.]
