Yes they are getting worse.
CC all your DMCA's to Oron to :
[email protected]
If the content isn't removed within 24 hrs from Oron, send an email directly to Leaseweb and ask them to enforce their TOC otherwise you will hit them with legalities. Leaseweb reacts faster than Oron acts.
BTW ... want to block your content from being stolen as much? IP block all of Leaseweb from your servers. We found when checking that much of our stolen content was from their IP's as they host Oron and other file locker sites.
