The sites create a tremenduous amount of money from these bonuses. First of all players 2/4 and over proboly generate enough rake to cover the cost of the bonus.

Secondly the players under 2/4, most players that play poker dont win at all, so when the loose their money it flows to the better players who build a bankroll and move up the limits, and then in turn generate more rake.

You figure maybe 20% of the people who do the reload bonuses just cash out and dont put that money back into the site (after they pay much of it back in rake). I estimate that number from the estimate that, 5-10% of players are winnimg players and then most of the people that bonus whore are proboly winning players so I think the 20% is pretty accurate. Loosing players who whore just throw the money back into the party community.

Then they attract much more players and since they have more players on their site more people want to play there because there are a lot of fish. And if they keep doing bonuses they keep the players playing at their site and not at other sites.
