I suppose whether it was right or not is dependant on what rules the forum owner thought it had broken. However, I think the point I was trying to make, is that it was a similar thread to this one, in that a question was asked, answers given in good faith, and then taken exception to. However, the difference being that the evidence of that discussion have now been censored deleted, giving perhaps a false impression that this site is worse than others.
I know threads are often locked on this site, and perhaps deleted if they get really bad,in rare cases, but the one on FB to me looked pretty good natured with lots of useful suggestions (including yours).
