You are so entitled... Because of you most nice things have "no limits but...". Not cool stress testing someone's infrastructure. Not cool. The author of this post is more than understanding, tried to fix it and offered a solution even after blocking them. On a free service.
Show us what you have done.
>You are so entitled
That's how agreements work. If someone says they will sell a hamburger for $5, and another person pays $5 for a hamburger, then they are entitled to a hamburger.
>On a free service.
It's up to the owner to price the service. Being overwhelmed by traffic when there are no limits is not a problem limited only to free services.
