Welcome to the internet. Install pfsense/opnsense and run your own firewall at home and you'll be shocked at the flood of non-stop portscans hitting your ip getting blocked. This is par for the course and there is nothing you can do to prevent it, you have to build systems able to mitigate, offload, block bad actors. This will always be the case.

Any free service that has utility will be quickly scripted against and used to make someone else money. Build accordingly
