How to empty a buffer before it gets to0 large

Question

I'm browsing with erc to some channels which are mainly used by bot request. Therefore the buffer size will scale up very fast. Since It's a read-only buffer I cannot empty it by hand. Is there a way to tell Emacs to empty a buffer if it reaches a specific size?

Have a look at my configuration for clearing eshell. Not sure how to clear if it reaches a specific size but it might be a start link — Sparx, Oct 09 '16 at 11:13
In what way is the buffer read only? Perhaps you can simply turn the read only flag off by using C-x C-q? — Mathias Dahl, Oct 09 '16 at 15:18

I just found erc-truncate-mode. You have to change this variable erc-max-buffer-size

Maximum size in chars of each ERC buffer. Used only when auto-truncation is enabled.
