An LPFM in a pissing match with another LPFM is nothing new to the FCC. Happens all the time. If average consumers are concerned about the operation of an LPFM by filing a complaint and make it even more public using social media as additional leverage to some extent, you'll ultimately get more traction.
That being said..The fact that this particular LPFM ran obscenity-rich programming for a week before someone other than KVSH-LP complained, seems to illustrate how much gravity the Commission gives to these stations.
As I've said in other posts, I generally consider complaining to the FCC for things like no legal ID's, or things that really don't matter, a last resort. If you're REALLY bothered about whatever violations you think this is making, then why not reach out to the licensee and let them know of your concerns? I bet that more than half of these LPFM's are either run by volunteers who are just focused on doing their own thing from a programming standpoint and aren't paying attention to operating technicalities. Why not give them an opportunity to come into compliance by reminding them of their responsibility in a adult and professional manner? It's not like a couple E-mails or a phone call is going to cost you anything.
Besides, the fact than any LPFM actually has a listener or two, in spite of the reason for listening, will probably thrill the station no end.
