Why suspend people who is nice enough to say " Thank you for sharing"? For those posts that require a reply before allowing me to read or watch what's it all about, I just simply write "cccccccccccccccccccc". Since I don't know what I am going to see, there is no point for me to write too much. Then once I see the content of the post, there is also no point in writing anything meaningful 'cause my post will be lost in all those other "cccccccccccc" posts.
So if someone writes "Thank for for sharing", I think that is quite appropriate already....
PEACE!!!
