if you normal dc but exciting game you will lose your items and gain no points, also devs have said in a youtube video if you dc alot of times you will likely get a temporary soft banned, i believe if you dc over 80 times in a month or something, they keep records, I've dc alot tho no problems. The only time I've been able to keep my items is due to a in game crash, or if killer host dc, old versions of dbd you could dc by ethernet and keep your items and points they fix this along time ago.
