It always depends on the context in which such or a similar number is used.
In German-speaking countries, 88 is a synonym for HH, which in turn is an abbreviation of the Nazi salute. Therefore, certain symbols are officially prohibited here: SS, SA, HH, 88, 2004, unless the user can prove that the symbol used has a different background.
For example, HH-SS 2004 on the license plate.
HH is the official license plate code for the Hanseatic City of Hamburg, instead of Heil Hitler.
SS stands for Susanne Schmidt instead of Schutzstaffel, and April 20th, for example, would be Susanne and Markus's wedding anniversary, not Adolf's birthday.
In Asia, however, 88 could have a lucky symbolism, and in Africa, it's a number like any other.
But since this is about the game and not about the individual user with a locally questionable name, such a discussion should be continued in the forum and not in the game thread.
