issue resolved on my end. deleting my previous comments. it seems that my password was changed for security purposes and I didn't get any email until half a day after. all other Freebitco authentication emails arrived late as well

Yes, I get "incorrect login details" error message. I only have 1 account and I do not have time or interest to abuse the website as I only use it to keep some crypto. Something is fishy about randomly deleting accounts though. Freebitco gets to keep the money without proper investigation, don't you think.
