it was a joke my dude, don't take it too seriously. maybe i don't want to get verified? :)
LE won't care if its 29.55 or 50 as long as they can establish money exchange for solicitation. as plausible deniability goes if we (me, you and others) fallow all rules and common sence when we establish contact - we should be good.
worst case: dont even give them any excuse "thats the money i had" the only line you want to say is "i respectfully refuse to answer your questions and want to exercise my right to remain silent until my lawyer arrives"
