why did I get a "can't post bad information error" when trying to post the following in a reply

Another alternative which I use sometimes is to have an external USB drive with Card reader. I have a battery powered  *w*d pass *port and all I have to do is put the card in the slot and the drive automatically back it up without needing a laptop. Nice device and pretty cheap. Mine is 4TB.

Apparently mentioning that well known drive brand and model triggers the Error.

The word "passport" is a banned word because of the incredible amount of spam that comes in using it.

Oh ok.... good to know! Too bad the forum software doesn't return a precise errror it took me a while to figure out which word it was . Thanks
