The last time I used it one of the common hacks was adding 50 makers to a single app launch PH also openly condoned mass email blasts and tweets to drive votes which just rewarded whoever could push the hardest on promotion
In contrast Hacker News discourages asking people for upvotes and even treats it as a negative if you do That longterm focus on signal over hype is probably why HN still feels useful today while PH lost its way
