If your post got deleted, you weren’t following one of the rules and a moderator deleted it. See the rules here to get clarity on which one you were breaking. If you can’t find the #MEC in search results, then you were blocked by one of the moderators for breaking a rule and permanently removed you from the group. This is irreversible as the blocked members list is over 1,800 people on it and it includes no search feature to find you and remove the block. Sorry that happened!
