I'm really spechless someone really DOES care about something as puny as police tag on a trader. Circumstances are such, that most of my noobs in vipers get an LPI tag after attempting to get an IMG tag by doing IMG missions on IMG territory. They either have to double-bribe or rely on others if they want to avoid it.
Face it - LPI tag is the easiest and quickest to get regardless how far away from what you plan LPI is. And it is sometimes such a pain to get rid of, that setting up a new char often appears as the best option.
So chill the bleep out and start flying with fraps on to snoop out speed modders if you're THAT keen on keeping the server's behaviour in check.
