Yes, the hosts sometimes miss things. Someone likely reported your post as having a scammer's number in it, without checking to see that the crooks were spoofing one of Apple's own genuine phone numbers. Then in turn, the host didn't notice or check to see what the number was and edited it.
That said, a lot of scam phone numbers reported here do call directly back to a scam operation. So speed was likely considered more important at editing the number than to see who it belonged to.
So why do the editing at all when anyone reading the topic can also read it's referring to a scam? Because if left, Google and other search engines pick these numbers up. In turn, they show up in links for "Apple Support" with the phone number. We've seen numerous scammers do this themselves in posts on this forum. They'll drop a dozen or more posts, often under three or four new user accounts, asking "Is this a legitimate number?" The giveaway is they post the exact same text over and over in new topics. And the purpose for that is what I mentioned. They want search engines to pick up "Apple Support" with their phone number.
Because of that, the hosts try to remove any possible scam numbers as quickly as possible.
