Do you really think CSIS, CSEC, or the RCMP really care or know much about the fediverse? It is not the place most of the people are on. Now the five eyes may see the data coming out of your place and have you on a list just for using a non-commercial thing to get away from trackers, but seeing as how you are here I am sure you are on their lists for other reasons to.
Not saying that you are a bad person or anything but rather someone who respects privacy, and the global security system does not like people who respect privacy.
