mnko posted about 10 in a row in B&S a couple of weeks ago.
Too many Qs posted too quick or too many answers in same Q in a row and the robots at AB headquarters think that they are under attack from say adverts spammed out by some companies system ...like an ambush.They will automatically ban you from posting again until the next day when Mrs Ed reviews the situation and decides whether it is coshure or not.
Its worst on a weekend as you have to wait till about Monday afternoon till you are allowe back into AB.
