Okay, I'll start. This is done for humor, of course, and speaks sarcastically at some of the stupid/sick stuff we find in the H-entries that don't even try. This is for all non-abuser characters, or characters that wish to avoid doing big wrongs, although, its like as not that some wrong will occur.
1 - If an authority figure you have known well is suddenly replaced, immediately be on your guard.
2 - If a close relative or someone you think of as such suddenly starts advances you don't like, take this as a sign and avoid.
3 - If someone has recorded your wrong, unless it be of you dumping a body of someone you didn't kill in self-defense, tell everyone you know yourself. The extortionist will just tape further wrongs they make you do, then release it anyway.
4 - Ladies - it may be that, while you are sleeping, girls from legit anime are sapping your strength, so that they may send guys into orbit who may have seen their panties in the laundry room, leaving you unable to stop a wildly grinning DMV clerk.
5 - Guys - Accept no gifts from anyone. They will backfire. If something you do accept gives you power over women, use it to learn all their favorite stuff and buttons to avoid pushing. It'll slow down the sex, but leave you alive and whole.
6 - Read no old diaries. Uh-Uh.
7 - Haunted places probably are. Leave them. Haunted places with 'legends' of molesting ghosts should be Molotov-ed repeatedly.
8 - If a young couple decides they want to have sex, do it right away, even if one is not 100% sure. This will avoid the wacky misadventures that have each of them with up to 15 partners. Don't use force, save the force of the argument that the relief will prevent further stupidity.
9 - If a girl always undresses, bathes and is otherwise never seen naked by any others, bounce a ball in the direction of their groin, and be prepared to apologize. But otherwise, she may have a secret most won't like.
10 - Take a part-time job chopping up squid and octopus. Get very good at it. Like a good burglar alarm, this skill will force the tentacles to move on to the next house.
