No Illegal Activity
rule 5 of 10
Posts and comments may not promote illegal activity. Since laws vary between geographical regions of the world, consideration will be taken as to where the activity is promoted. In cases where no jurisdiction is specified, the laws of the US, CAN, UK & AUS (where most users reside) will be taken into account based on reasonable legality. When a violation occurs, the burden is on the user to prove that activity is legal in the OP jurisdiction, citing a credible source.
