i don't know how possible it is possible but you could try riding a program or something (probably just trying to detect if there is a "Update" Word in there)
which either :
1.gives you a massage
and/or
2.delete the post
but if you choose to do the 2 option i also suggest having some sort of codeword to put instead of the "Update" Word in case some people can't either ä or ü with whom we could write Üpdäte
practically killing fire with fire
killing a clanker with a clanker of our own
