User blog:Speccyemerald/How excatly do the mods and rollbacks know that is a trollpasta and what isn't? Why have the rules on pastas been tightened?

Seriously, how do they do if they did the right thing to a pasta that is reported as being a troll pasta or related?

When is the line drawn? Also, why have the standards been tighted to the extent they have been? Do you think that this is necessary? Please share your thoughts if you can.
