Not sure if this is the right forum, but these are just some things I noticed while playing. I personally find all of these items to be borderline cheating, since they all rely on exploiting holes in the game mechanics.
1. Coven: Dead shouldn't be able to taunt.
Medusa victims often use taunts to out medusa.
2. Coven VIP: Poisoned VIP leaving
Poisoned (or found) VIPs in will sometimes leave to "give town a chance", since that assigns a new townie as a VIP. This severely skews the game to the town's favor since that confirms the newly chosen townie and narrows down the pool of evils. I understand that leaving after being found is hard (probably impossible) to police, but maybe poisoned VIP leaving should be an automatic town loss.
3. Dracula's Palace: Youngest vampire leaving
Basically the same deal as #2 - youngest vampires who are found and repeatedly jailed or rb'ed will sometimes leave to give the other vamps a chance to convert/kill. This is once again very hard to police, but needs to be considered gamethrowing in a way. The whole mechanic of only the youngest vamp being allowed to visit victims is done for a specific purpose - in classic mafia, the Godfather will visit instead of Mafioso if the Mafioso is jailed. The vampires operate differently for a reason. If a youngest vampire is found by town and rbed continuously, then that is how the game was intended to work, and more players need to abide by it.
4. Coven Lovers: Very unbalanced towards single evils
Town-evil pairs pretty much gives town an extra vote and a vigilante without the consequences of suiciding. Most town-evil pairs go for town win since that is way easier than claiming a fake town role for the evil lover, and going for an evil role. Chances of town-evil pairs should be lowered.
