By the way, my post title was changed by someone else. Paypal is NOT banning anything Bitcoin related, they are only banning Bitcoin exchanges for fiat currencies.
Sadly, this is a well-known issue on HN:

Although that open letter received a lot of attention, nothing has changed since then: No transparency which admin "corrected" the title, not even an indication that this kind of manipulation happened at all. So you as the submitter receive all complaints about the crappy title.
@pg: Note that I fully understand that we HN submitters should not be encouraged to use link-baity names for our submissions. And that we should prefer the original title wherever feasible. But some articles' titles are crap. Some are uninformative, some are misleading, and some titles are even wrong. If it is recommened to remove link-baity numbers from titles ("10 Ways To Do X" -> "How To Do X"), why isn't it equally feasible to replace misleading/wrong titles with informative/correct titles?
I suggested via email that they could let veteran users flag inappropriate (link-baity/editorialized/inaccurate) titles and have moderators change them in that case, but I never received any answer.
