I flagged some (most? not sure) of them as booster comments, presumably by friends trying to help the submitters out. HN users aren't supposed to do that and YC founders are given strict instructions not to do it (and scoldings when it happens), but it's impossible to prevent completely. People's friends try to "help" them and don't realize that it's actually the opposite of helping.

See the "Comments" section of the Launch HN instructions for YC startups (https://news.ycombinator.com/yli.html) for an example of how strongly we emphasize this.

If I see this many questions that could have been taken straight from an FAQ, all followed up with “great question, we do so and so..”, my alarm bells go off. Shady marketing indeed.

There was even more before. Some has been removed completely.

I'm also confused. They seem positive and constructive. Do mods detect that these are some kind of automated bots?
