Yeah I guess one of the main points @ignoramous trying to raise, is that PG should consider be explicit about this by emphasizing this guide is merely a starting point and is not “comprehensive”
I think the guide actually kind of already covered this by saying
Like all of our guides, we are going to cover the general best practices and provide helpful tips, but your individual situation may be different. You should always research and plan according to what you specifically are doing
But maybe not as clear as @ignoramous expected.
Many protestors got flagged on scene and traced back to them for their online activities. Being a protester / activist, you need to separate your online / protest / real life identity. This is not something can be included in this guide, but crucial for your safety.
