Tried to do a google search but didn't find anything on it.
Can Broadcast Square be used to avoid taking a tag but still take the credits from Geothermal Fracking?
Firstly, Corps don't take tags, they take Bad Publicity.
Secondly, yes, as the credits don't rely on you taking BP first (as they do with Profiteering). They're two effects that occur from the same source. You couldn't use the Fracking credits on the trace though (same as you can't use Siphon credit to pay for tag-dodging with NACH).
Oops my bad, yeah I meant BP. But gotcha, thanks!
