For me there is a clear difference between shilling and having an opinion about something and expressing that opinion strongly. A shill blends into the environment, but the

majority of the posts are concentrated on obtaining one specific goal. You only need to browse such a users post history to isolate them. The shill will troll some threads and

post something with little value... but when it comes to his/her main goal, they will post extensively and with vigor. The OP is 100% correct in saying that these people needs to

be identified and labelled... but it's not going to be easy to differentiate between a shill and someone who feel strongly about a subject. Many of these people joined in,

because they felt strongly about what they perceived as censorship and not really anything to do about block sizes.
