It's getting tougher as time goes by.
Skype dropped me cause I didn't use it for 3 months? Had no info on user name & ID so after trying various combinations I asked for my user name via my e mail address which worked fine. Then came the ID. I tried all my IDs, nothing worked. Submitted new ID, which is a fairly uncommon 5 letter word followed by 12345.
"Not secure enough"
I type in fuckyouyouasshole, it responds:
"at least one number must be used."
I typed in another user name I use with 9 characters...it worked!
Over the years I've been told:
"no more than 3 sequential numbers in a row with increasing or decreasing values"
"must be 6 characters or more"
"the numbers 6 & 9 cannot be next to each other" (I was trying to use 96)
"that user ID is already in use" NO SHIT DUMB ASS, IT'S ME!
