But I was surprised when seeing a few users including Hero/Legendary replying there where they should report the thread
I did report that thread at first sight. And by the numbers I'm
not one of the best reporters. And yes, I've seen later on the first replies coming.
Now, on a not so "fighting" note,
sometimes those newbies may need to see a first answer telling them they are doing it wrong (and I was sooo close to reply and tell that he should not do this again...)
All in all, don't think everything so "black and white",
sometimes the truth can be in the middle, although
in this case you are certainly right: all the current replies seem focused on how useless the faucets are instead of telling that OP was breaking the rules and his post will get removed.
A post can only be reported once.
I think that a post can be reported once
by one account, since my report for this same post also tells it was a good report.
