You can create a plugin using hook location bbcode_parse_start and code like this:

if (defined('STYLEID') && STYLEID == X)
{
   $dobbimagecode = 0;
   $dobbvideocode = 0;
}

where you replace the X with the styleid of the NSFW style. Then you need to truncate (empty) the postparsed table to see the results (the images seem to be affected immediately, but you need to clear the postparsed table to affect the video tag).
