I’m in the hosting industry and I’ve been using RRProxy Reseller which is now part of the CentralNic Group. Using them would be way better as I would get abuse reports forwarded to me to resolve. I’d normally just forward the report to the registrant and then tell CentralNic that the report has been resolved. I’d only take action if it it were very extreme such as CP, Terrorism etc or law enforcement contacted me. You also have the option to approve external/internal transfers instantly whereas using domain providers would take days to be completed. You also control domain locking, unlocking eg clientHOLD options so even if you or CentralNic were to put domain on hold you can then just go unlock it back and even if they do lock it if you don’t let them know you resolved the report just simply replying back to the email which they never really (also you still get access as a reseller to unlock it again yourself for the client) you can also still get the transfer code and just transfer it elsewhere locked or not. So conclusion wise you have more control than you would with normal providers.
Hope this helps.
