Hi,

That URL message can be detected as Spam from Bot code without any problem...

Your issue seems to be caused due that Bot instance deployed ("Banglago") is too slow to detect the "new user joins the group" event, and any spam message received before the Bot know that it is a new user won't be considered Spam (the Bot didn't know that it is a new user yet due it is to slow!).

So, check your deploy network latency/delays, check firewalls, proxies, deploy the Bot with a Webhook instead polling, etc.
