Nobody in UN has ever coordinated with a police player to pirate ships using Tlagsnet. No. We will never use Tlags for piracy, and the police are not using Tlags for piracy. This is disinformation, possibly not the fault of the OP - occasionally people just make stuff up and he could have been disinformed.
I checked every log I have access to regarding UN players in group with police players. The most Tlags info sharing was for lawful fight actions, which only happened twice so far.
What is actually happening is that police players are sharing tlags data to other navy and police craft to hunt federal snubs. UN groups up with that group when fighting federals. We are not using TLAGsnet to break the trade event, and I've asked around to make sure that it isn't happening.
They're only doing it when federal fighters and caps use the tradelanes anyway. If anything TLAGsnet is useless for the Unioners as we're pirating Federal traders who use the jumpholes right next to our bases. Placement is far more useful than TLAGsnet.
