The problem with removing game titles is they often help flag there is no point joining (eg someone has hosted to test something, or has a player name in the title because they just want to fight them, or dont want people with x cpu or y number of games, or will be hosting a ffa or a vs AI teamgame, etc), while all welcome can be used to indicate youโre less likely to be kicked.
If people are hosting with offensive titles then taking a screenshot and making a report would be better than removing all titles.
