[wp-hackers] admin-ajax.php and $_GET?

[Otto]

GET and POST serve two entirely different purposes, and POST is the
correct one in this case.

GET is for situations where you are getting some data back from the server.
POST is for situations where you are sending something to the server.

The main difference is that browsers can cache the results of a GET
request, and if you do the same GET twice, then the second time you'll
get cached data, it won't hit the server.
