some people are already submitting games to use the jam as free advertisements, are you going to take action on that? 

Yes Im removing them as soon as I can, Its a judgement call of course each time

Yes, the closer it gets to submission, the harder it gets to differenciate them

Shoot to Survive is definitely one of them ...

so ive just found out that .io allows you to report jams with the reason that they are not for this jam. then they will be send to the jam host (in this case javid). so they can delete them if they find it justified.
