I would avoid any "blacklist" formed by a single fleet, specially one many people are not very happy with.
If you wondering about blacklists, some fleets have a list of players who have caused major problems for other fleets and themselves in the past who they will not tag. Things such as openly expressed fleet bashing, major bans, Scams, dishonored loans and other things will get people on such a list.
That being said unless you've done something seriously wrong or pissed off a lot of people you most likely are not on any such list.
