Books with bad LGBT+ representation. Can be reinforcement of negative stereotypes/tropes such as: all lgbt+ people are predators/evil, only queer as a result of trauma, and "turning someone straight". The only queer characters getting killed off or being the only ones without a happily-ever-after is also a pretty good way of getting on this list. Can also count books where the author claims a character is queer after the fact without hinting at it in canon *cough**cough* jkr *cough*
