Hello, to answer tour multiple questions
1- the purple ribbon is on creatures you have on your wishlist (or the other player if the ribbon is on one of your creatures)
2- if you're talking about a striked creature, it means this creature is already proposed in an other trade
Bonus : when you want to add a picture on a message, use site to upload it and put the url between [img]and[/img], don't use the joint files
I hope these answers are usefull
