This could actually be the easiest way to deal with it. You can technically remove the block via system firewall, but I guess the abuse is only for cloud VMs that Elest.io provides and not the BYOVM ones, so you can use provider firewall rules to enforce the limit.
Indeed, no issues at all with BYOVM, and for other VM we have full control on the firewall from the cloud providers and we can block outgoing traffic and limit incoming traffic to the tester IP, I will definitely investigate this!
