My dear, it's really the height of a hidden paradox. Frankly, I have tried to wrap my head around that part too of something being allowed but then discouraged and it keeps beating me hallow. To put it mildly, it doesn't make sense to me. Could that be that it's either I've a minimal grasp of English idioms or I simply don't understand basic English language 🤔. Maybe it's about time theymos reviewed that rule so we could understand it better. I guess it was made at a time when there was skeletal traffic here and the forum needed to coax posters to stay active but the rhythm has obviously changed now and it should call for a change of parade too.
