This past 2 weeks are servers starting to get hit a lot. And their bots just go crazy in PHP sites with session IDs. Earlier we have 1679 concurrent connections from them within 10 minutes as they get caught in a PHP site (a small one at that). Prior to this, they hit one of our servers 4 times over the last 2 days.

Anyone know if this bot respects the robots. txt ?

Looks like they are located in HE.

For now, I am going to block all their IPs.
