matches extended

Is it normal that matches will be extended with 30 days after 30 days?

it's not normal and is a red flag.

typically it's a payment pending contest, but sometimes a prepaid contest where the buyer doesn't really know what they want and probably has about 30 personal messages he has to sort through.

Eeuhmmm. If a prepay customer has this option, than the participants must also have the option to remove their design. :(
