Although I love trolling my friends, I totally agree with what you have said. Trolling(some said it's attack) is not something all-bad. But it is surely unhealthy if trolling is overwhelming in a community or forum. We can troll others in other platforms occasionally. But we must know that Steemit now is developing as a center of quality content. This healthy atmosphere should be maintained by all users.
