Charlie , I think they consider it to be a surreptitious form of bumping up the post .
I know it was probably genuine in your case , however its a generic solution to all their posts .
It should be a short term ban , probably no more than a week or so .
In future pm the seller if you are interested .
I was also banned for a similar offence a few years back .
