While unlikely, give the benefit of doubt - a few instructions on how to post properly is the right thing to do....if the behavour continues, or its seen as deeply not appreciated - then we don't want those types of people here.
I kindda live by a two strike rule - burn me twice (maybe because I'm soft and will try to see the good in people), but never a third time.
I give people one chance mostly, two at a pinch. I haven't heard back from my last message outlining a few helpful guidelines...Probably won't. Let's see how that person rolls out from here huh?
