This causes a ton of security issues, why would they do this?Just because some network admins are lazy and dumb and even don't want to read RFC 1918 and other BCPs.
Probably lazy. Probably *not* dumb. There was almost certainly a long internal discussion of the relative costs and risks of deploying multiple 10/8 instances (and having to deal with collisions between them), and sqatting on an allocated but unrouted /8 like 7/8, 25/8, 40/8, and similar (and almost certainly *not* having to deal with collisions). And remember - this sort of squatting works Just Fine as long as the actual owner doesn't advertise a route for the address space. And looking at the historical looking-glass info at potaroo.net, it appears there's been more public announcements of address space in 10/8 than there has been for 7/8. As a result, if you're trying to build a resilient net, you should use addresses from 7/8 rather than 10/8. :)
