What you have done is correct. I don't know why you would have needed to
remove the '$'. Did you get an error and if so, what?.

The regexp I gave was just intended to be an example regexp. The
BAN_LIST is actually a list of strings so regexps in the BAN_LIST have
to be quoted and enclosed in [] and comma separated if more than one.

Also, it doesn't matter in this case because \+ and \. are not
meaningful string metacharacters, but it never hurts to define them as
raw strings like, e.g.,

GLOBAL_BAN_LIST = [r'^[0-9a-z.]{8,}\+[0-9a-z]{4,}@gmail\.com$']
