As you had already seen from the title Falstaff had an idea to organize something like a blockade competition. If you are interested and have in mind a amazing or funny blockade you can participate. Ways to participate:
Joining Joi's discord server (there is a channel for this purpose)
Replying to this forum with your blockade like this example, below:
Emergency Blockades aren't acceptable
You can send only one blockade but it could be someone else's blockade.
Also he is thinking to make a vote for the best or funniest blockade but this is not sure for the time
