If the problem are really the bots who update cards Thousands of times a day why punish the player who want sell or rent a card for this ?
I mean it would be very easy: Every player has 1.000 listings free every month and listing 1.001 and more cost something. In this case I would be even fine to take 5 dec, but the normal player should IMO be able to list a few cards for free.
if your card is rented regularly, you never pay the 1 dec. again. after every rental, the time period to cancel is extended by another 30 days. if someone rents your card on the 29th day. it stays on the market for 30 days longer again. so you only sort out the cards that are not rented anyway. it also has advantages for us. so we have cards that no one rents anyway directly to hand and do not have to cancel the rentals first. because we see so which cards. are rented and which is moldy there for years^^
ok but you don't tell anything about my suggestion.
Why not let every user 1.000 listings free every month and take fee only from 1.001st listing ?
In this case you would reach the goal to stop bots update card prices Thousands of times a day without affect the normal user who list a few cards.
As I told I am even fine if the first 1.000 in a month are free and from 1.001st it cost 5 dec.
i don't know, maybe it's easier to implement. or safer from fraudsters who then just use multiple accounts. maybe you want to use the opportunity directly to build in a dec burn. i don't know. but i am but i think that the cost use ratio is excellent. and if only after 1000 transactions a fee is incurred. then all my cards that have not been rented for months remain on the market. even now just put your rentals before the patch and you have no fees and in 30 days only the cards fall out that no one wanted anyway ;)
Because they are money grabber and instead of ban bots they milk players, all changes past year are in that direction, first ghost card, then level cards, now this
