Maybe they triggered a filter and were deleted automatically. There's never a mod present to delete them. Hell, they leave the spam up for eternity.
Why were my quotations from "The Hitchhikers Guide to the Galaxy", beautifully translated into Hindi, deleted?
My thoughts would be maybe a "random coincidence" meaning the modbot randomly deletes a question here and a question there, a couple comments.... Etc JUST so IF there really is a site boss or owner they can show "look! We have been doing our job!" A question a day. Two comments a week.......
Maybe the Mods are superehuman and have the power to not see spam, but they are racist pigs who are afraid you are telling other Hindu-speaking people some sort of terrorist thing. Because that's, unfortunately, however untrue, the first thing some people think when they see scripture of Middle Eastern countries now.
