上下文：我最近做过，也许经过一些运行后，它突然不发送消息也不返回语法错误，这是代码

            await message.channel.purge(limit=1)
client.run(token)

它曾经几乎可以完美运行，现在ctx.send无法正常工作，但是我从Lucas的discord bot教程中学到了这个badwords过滤器的client.event（）后，就制成了该机器人。

您需要在process_commands()事件的末尾使用on_message才能使其他命令起作用。 Read more

@client.event
async def on_message(message):
    bad_words=["Fuck","fucking","fucker","shit","akshith","bitch","Anika","anika","sabertooth"]
    for bad_word in bad_words:
        if message.content.count(bad_word)> 0:
            await message.channel.purge(limit=1)
    await client.process_commands(message)

Discord bot突然不再发送消息了
