I agree with your point but there definitely is some brigading going on by the "pro-blackout" crowd. I moderate a small-ish subreddit (~6500 subscribers) and while our poll to blackout received overwhelming support including from well-known members in our community, I definitely noticed that after sharing in the /r/ModCoord thread our intent to blackout the thread started receiving a lot of supporting comments from questionable brand new accounts (or accounts with low karma/had never interacted with the community before). And this was without linking the thread at all - these users were clearly coming to the subreddit, finding the post and making pro-blackout comments to push the community towards a shutdown.
