Help me for my channel telegram please?

Sorry but I'm in a panic and I don't know where to write the question.
A person is trying to hack my telegram channel or have it shut down.
I am receiving numerous subscriptions to my channel from accounts that are probably fake or I don't know if they are generated
As if they had put the channel on a service that wants to grow subscribers to the channel BUT IT WASN'T ME
Do you happen to know of any telegram bots or some way to protect yourself from this?

Any telegram bot usually has spam protection filters, combot is the first one that comes to my mind not sure if it is still around.

Try making the channel Private or change the public link.
