Probably, something like this will work:

http {

map $http_referer $is_referer {
default '';
~^. 1;
}

map $is_referer $no_referer {
default 1;
1 '';
}

map $invalid_referer $zone1 {
0 1;
1 '';
}

map $invalid_referer $zone2 {
0 '';
1 $is_referer;
}

map $invalid_referer $zone3 {
0 '';
1 $no_referer;
}

limit_req_zone $zone1 zone=zone1:128k rate=50r/s;
limit_req_zone $zone2 zone=zone2:128k rate=10r/s;
limit_req_zone $zone3 zone=zone3:128k rate=3r/s;

server {
valid_referers domain.com;

location /click.php {
limit_req zone=zone3 burst=12;
limit_req zone=zone2 burst=10 nodelay;
limit_req zone=zone1 burst=100 nodelay;
...
