a non-spam important interest was removed - i wonder why ?

Tweet

i guess my contact should re-read the guidelines. but its very curious via the contact wrote briefly about a very important interest and the writing was totally NOT spam or anger or anything readers would object to, yet the writing was removed. can anyone offer " cut to the chase " feedback ? i.e. a bullited list of precisely the main stuff which would be removed, if posted. That, would be nice -- does it exist ?
