I am not too familiar with that forum but I think it makes sense over time some members will go there and use both forums. In the end, virtually every person associated with the forum has that link because of financial incentives.

If members here could make money at a different forum at $30-$40 per week while still making $70-$80 here, they will do it because they will receive an extra income. Now that there is a mixers ban here, it will probably expedite the sign-up elsewhere and if does not impact immediately it will definitely do so over time.

With alternatives out there, members will use other forums and with that increase in traffic and popularity will increase even if takes time.
