8th post here. I think this one may be it...
Imprison's Move Effect incorrectly claims the move targets all foes, rather than the user
Taunt's Effect does not enumerate how long the move lasts, and also uses "opponents" instead of "targets". An improved description would be along the lines of "The target is barred from using status moves. The effect lasts for 3 turns if the user goes before the target, and 4 turns if the target goes before the user."
Tearful Look's Effect is a copy/paste of the move's description and is very sparse on the move's effects. A better worded and expanded description would be "Lowers the target's Attack and Sp. Attack stats by 1 stage each. (Enter) Tearful Look bypasses accuracy to always hit, except during semi-invulnerable stages of moves like Dig or Fly. Tearful Look will even hit through Protect or Detect."
Teleport's out-of-battle effect has been removed as of Gen 7
Toxic Thread's Effect is a copy/paste of its description and does not match the quality of other Effects on the site. An improved wording would be "The target is poisoned, and the target's Speed stat is reduced by 1 stage."
Twister's Effect claims it has a 30% chance to cause Flinching, but other sources and the "All Moves" page say the move has a 20% chance.
Venom Drench's Effect on the "All Moves" page https://pokemondb.net/move/all fails to note that the move affects Attack, and just says Sp. Attack and Speed.
Venoshock's Effect claims the move inflicts double damage, but other sites and the move's description say the move doubles in power
Water Sport's and Mud Sport's Effects both say the type's damage is reduced by 50%, rather than 67% damage.
Wish's Effect is very sparse and does not really cover what the move's effects are. An improved/expanded wording would be "The user makes a wish for healing. At the end of the next turn, the pokemon in the user's location will be healed by half the user's maximum HP."
Zing Zap Effect is copy/pasted from its description and does not match the quality of other effects on the site. An improved description would be " The user deals damage and has a 30% chance of causing the target to flinch, if the target has not yet moved. (Enter) Pokémon with the ability Inner Focus or those behind a Substitute cannot be made to flinch.
What a ride it has been, but I have gone through all the moves and hit all the issues I've seen. Hope this list helps out, and thank you for the good resource! :)
