Well I wouldn't come back

And when people ask how my trip was, I'd say "oh they really don't want tourists there right now ... Check out this picture. I wouldn't plan on going there"

It accomplishes its goal of making tourists feel uncomfortable and less coming next tourism season. If their economy relies heavily on tourism, well, they'll figure it out. And if they don't, then that's on them. Be careful what you ask for and all that.
