I just read the article. Removing all unsourced
material, and how-
to's (as per [[WP:NOT]], can leave the article informative without
being a user manual for suicide.
Good response. Fixing is always better than deleting, where possible.
A how-to guide to suicide is not appropriate. An encyclopedic article
on suicide methods is. The article should includes statistics about
what methods are most used, etc. It should not contain detailed
instructions.
