Perhaps, but before we assume, can the load from pinging actually get so
bad that it can be used for a DOS attack?

Is that what Denial of Service attacks? basically repeated pings... that
would be one reason for blocking.

Not RPG related, but why do some people block pings? Granted, most

places

we can't do anything about it but at least if we understand the reason

(or

lack thereof) we can influence those we can.

Even if there's no response, if the ping resolves to an IP you're
good.
That's all that matters with ping.

Not true. Being able to resolve a symbolic address is only part of
the equation. Even with an IP address you may not be able to reach
that system (e.g., No route to host) for a number of reasons. Ping is
intended to tell you the host is reachable not just that name
resolution is OK.
