My b2evolution Version: 2.x

[2.3.0-rc1]

for several months now, i've been getting hits like this in my "direct b-hits" logs:

http://mydomain.net/index.php?blog=2&title=http%3A%2F%2Fwww.soeasywebsite.com%2Fsoeasycasino%2Fenosucu%2Fijani%2F&disp=single

sometimes the URL is injected into the "more" call, rather than the direct link itself.

it always comes in bursts of about 50 to 80 hits, and it's a different IP every single time, so constantly updating my IP block list does almost nothing.

i don't show hits on my actual site, so this spam is utterly useless to whoever's running it. but it just keeps cluttering up my database anyway, and every few days i go through and delete all hits from the new IPs.

is there anything i can do about this? or am i doomed to constantly sweeping up this digital detritus?
