If you are not a mod, you don't know what has been removed from the thread, but is also about the newbie's perception of what is said, not just the actual words. We used to have a member who would just post the word REPOST on posts and threads, in itself it is not an attack but because of her general tone posting, people see it as such.
Not everyone is using a PC, if I am on my cell I can't control+f, people on ipads and other tablets can't, you don't always know how they are posting, and it really doesn't hurt to see them again - sometimes the reps are re-releasing the same coupons but we haven't seen it forever, so its great to know people are finding them again if you want them, because you can go and look.
As far as no one being rude, personally two people who posted in here told me they were no longer posting coupons because of the response they got. I have no idea if more reported the thread for the same reason but not one person should feel like that when helping the community
