BTW, Shadar, if you're concerned about outside agitators, please look at who comments here whenever the topic is PA's municipal water  --  Steve Slott is especially interesting to read about.  

Here's a quote from the Wikipedia entry on trolling:

<i>Investigative journalist Sharyl Attkisson is one of several in the media who has reported on the increasing trend for organizations to utilize trolls to manipulate public opinion as part and parcel of an Astroturfing initiative. Teams of sponsored trolls swarm a site to overwhelm any honest discourse and denigrate any who disagree with them.  A 2012 Pew Center on the States presentation on Effective Messaging included two examples of social media posts by a recently launched "rapid response team" dedicated to promoting fluoridation of community water supplies.</i>
