Plus you will have to make sure none of your div ids matches anything in their element hiding list. I installed adblocker the other day and noticed whole bits of our page missing because I re-used the ad class for some content blocks in the same area.
In fact you could use this to hide content from people using it, just name a the content div something like adpage. Only downside is no message to them so they will probably just think the page is not working.
