Been seeing a lot more Underage users lately and realized part of it might be due to the fact that even with the Google Safesearch, Webnanny or other such 'childproofing' methods, They will still return the 'safe' content from E621 allowing said underage users to find or even sign up for the site..
..Might want to look into that. Especially with a lot of the NSFW fanart for certain child friendly shows and games being stored here and easily searchable, If undesirably, From Google. :P
