This account is weird. Joined months ago, rarely posts and suddenly decides to become a forensic analyst to dig through someone criticizing Stripe? I am seeing this weird behavior more and more on HN. Inactive accounts suddenly seem to come out of the woodwork to defend, attack critics when a YC company gets involved. Even asking innocent questions like: is there an alternative to what this YC company is offering is grounds for flagging and downvotes. I think the readers can make the call as to what is happening. I don't buy that these are just lurkers suddenly logging in after months of inactivity to focus on one thread, and I've counted roughly about 3 to 4 HN accounts that are doing it on this thread alone.
