pass
elif gdata["antispan"] == "on":
username = message.author
user = str(message.author)
try:
spam = antispam[user]
if time.time()-spam.last_msg_time <= 1 and user != "Our AfterLife 我們的來世#9472":
timeouttime = timedelta(minutes=3, seconds=30)
await message.author.timeout(timeouttime, reason="洗頻")
embed = discord.Embed(

if gdata["antispan-ch"] == "none":
if gdata["antispan-m"] == "msg":
await message.channel.send(f"{user}因為洗頻被伺服器禁言")
elif gdata["antispan-m"] == "embed":
await message.channel.send(embed=embed)
elif gdata["antispan-m"] == "embed+msg":
await message.channel.send(f"{user}因為洗頻被伺服器禁言", embed=embed)
else:
try:
channel = self.bot.get_channel(int(gdata["antispan-ch"]))
if gdata["antispan-m"] == "msg":
await channel.send(f"{user}因為洗頻被伺服器禁言")
elif gdata["antispan-m"] == "embed":
await channel.send(embed=embed)
elif gdata["antispan-m"] == "embed+msg":
await channel.send(f"{user}因為洗頻被伺服器禁言", embed=embed)
except:
pass
except:
spam = antispam[user] = Antispam()
spam.last_msg_time = time.time()
def setup(bot):
bot.add_cog(antispam(bot))
