Oh no, but I already added some stories I remembered that I'm reading huhu, is that a bad thing? Shimmers
You only added a few, it should be fine.
From now on just be careful and save your lists off-site (e.g. browser bookmarks, spreadsheets, mangaupdates). Especially as recently I talked to some people who had their lists remove titles they added.
WTF HAHHAHAHHA NOT WORTH IT, JUST DUMP HIM! I FEEL BAD FOR HIM JUHUHU
