I really think that people shouldn’t be locked out of the black market when there is a special event going on that involves limited-time items in the black market. I’ve been kicked out almost every day since the new squishies and event items were released, which has made it basically impossible for me to purchase the special event items. It’s really frustrating and takes away from the fun of the event because I don’t have the opportunity to buy the items which means I can’t fully participate.
Edit: I want to note that on most days I’m locked out after entering the black market just once or twice. This is not due to me trying to buy items every shop refresh. For example, today I was kicked out the very first time I tried to enter.
