How long do these usually last, I've heard up to 24 hours, and currently going on 3 hours for myself. Is there a set time limit say 12-24 hours?

I've never been restocked ban here on subeta. I've been restocking all evening. Are you sure you are really banned?

Restock bans exist on Subeta? o_o;

Yeps, if you buy too much high rarity items in a short time, you may get banned

o_O

I learn something new every day.

Yup restocked too many rare/super rare items to turn into crystals xD
