i have proof (for myself at least) that the report option for "bad names" does nothing
i now got 2 people in my friendlist, one for 5 weeks and the other for 4 months
one is basically named "hang yourself" (just with numbers and stuff so im not nameshaming, 5 weeks guy) and the other one basically named himself "slit your throat" (the 4 months guy)
i found both of them in a match, reported them and addet them. both are actually really chill people and they had no problem with me reporting them.
to you this might not be proof or mean anything, but to me this confirms that the "bad name" report option is just like bad player. it does nothing. it needs a manual review or nothing will happen.
