Holy necropost batman!
That said, when posting our opinion we have to ensure we look like somebody who is posting his opinion that is not necessarily the same, not somebody who is only trying to start a fight (for example, if an Wii U fanboy registers on an Xbox One fan site only to thrash the Xbox One and contribute nothing constructive to the community). That said it depends of the respective site rules, though.
On an on-topic note, it seems Casiokingdom is working again, but it's infested by spambots
