We have had sporadic problems with public posts offering international trades of patented varieties. To be clear, public posts offering international trades and public posts offering patented varieties are against the forum policy and a new clause in the TOS has been added to make that clear.
The admins also would like to hear if you receive any unsolicited PMs asking for such. We are not trying to be police for all actions, only to prevent users that are bothering multiple people asking for such trades.
