ummah.com is mostly populated by hyped young people, not much grown up conversations, a lot of free mixing

salafitalk.net is probably one of the most negative forums out there...nothing but hate on that forum and people with terrible adab especially towards ulemah

Islamic Awakening..also has a lot of people with bad adab..and hatred for various ulemah...but its not as bad as salafitalk

marifah...not sure about this one
