Thanks! I already had done something to avoid this but forgot to update the code after making the mention detection case insensitive. The bot thought you were a different person than the quoted one because bttzed03 !== Bttzed03. It should be fixed now.
Subscribed thanks for this @TryNinja. Waiting for some quotes and merits to pop up to see how it works. By the way does this bot have prompt message when you already subscribed. Like "The UID you write already been subscribed" or we can used it both on laptop or mobile device? Cause some using laptop at home and when he uses his mobile he can also check it out for updates. Anyway great work, will tell you if something odd or came up from experiencing this bot.
In this case, it's better if you use the same Telegram account on your laptop and mobile device (the messages are synced). If for some reason you need/want to have a different Telegram account per device, you can use the same username/UID in both of them. I haven't tested it extensively though.
@Little Mouse, I have added the /alt command that lets you choose a second username that triggers notifications. In your case, you can do
/alt LittleMouse to receive notifications when someone post @LittleMouse, littlemouse, etc...
