There is no way to confirm who or where guests are coming from. I am sure that NGO's read or monitor some of the content posted here, especially in the Conservation threads, but I am not sure they learn anything they don't already know or assume about the recreational fishery. DFO also pays attention to the site and we have had contact from the police in the past when a particular post was problematic because it was made in a public forum. That is why we warn members to be careful about what they say online, as it can lead to challenges for them from a legal perspective. Having said all that, I don't think this site is any different than any other place online where people express their opinions on various topics, so I wouldn't worry about what group is reading what is posted here, unless it is threatning or defaming in some way.
As for the number of guests you see right now, this is the time of year where where our traffic increases given that we are in the busiest part of the fishing season. When people use a search engine to find information on fishing in this area, we often are at or near the top of the page, so that explains some of the higher numbers.
