If you’re not sure, you can just use the ‘report’ button to the moderators and let them review the matter. You will have some who skulk the site by trying to camouflage with the rest of the population.
Just report any such post to the mods using the "report" button - the button on the bottom left of a post - and they will review the post and take whatever action they deem necessary.
As others mentioned, please help us out by reporting those. Even if you are not sure, just report it and tell us why you are suspicious and we can check it out. Thanks
Could you give an example of what you consider "not legitimate?" Or are we talking about the Kool-Aid brigade not liking posts that doth dare speak against something Apple does? I've noticed a trend in recent years to call people spammers or trolls when someone simply disagrees with their opinion on something as if no one could possibly hold the opinion that Apple isn't always right (let alone in the political forum).
Likewise.I'll chime in and say don't ever think that reporting a post is a waste of time. I report posts all the time and I always get something from a moderator saying that they're investigating. The staff on these forms do stay on top of things.
