for shit sakes moderators 

You keep deleting my contribution even though it's true, and no i'm not making it up. how do i know this? my best friend helps to set up concert venues and has been doing that for 3 years now.  when a microphone is inclosed in a concave divice or even when a hand is holding the part you speak in, it creates a loop for the sound thus causing minor feedback. sometimes it comes in the form of echoing distortions and other times it comes in the form of howling and screaching. so moderators and those who keep deleting my contributions, for shit sakes. 199.101.61.190
