For past few days, my site "ditii.com" is completely down because of heavy spamming. Spammers are sending 500 trackback & pingback spams every minute, and draining all server resources.
I've tried to block spamming via HTACCESS but that's not working. I'm truly sure, I've done something wrong.
My blog is installed in /blog folder, and I'm accessing it from the root.
May I request the experts here to help me getting the site back to life.
