With the reputation that IRC in general has gotten over the years, I wouldn't be surprised if any IRC-like communication is declared malicious...
They can declare what the fuck they want, it won't change the fact it is legit and we will use it
Not saying it isn't legit (and if the problems get too bad it can be disabled as mentioned above or we can use DHT or something) but I've seen a couple AUPs that explicitly mention IRC as something Not To Be Done. Quick google search shows
a thread from 2003 about a datacenter that banned it.
Get as mad as you want at this, a lot of people don't even know what TELNET is these days (recently went to a meeting where someone tried to explain the concept and how it differs from the web).
[Edit] Will "excessive twitter activity" be soon
seen as suspicion of a botnet? What about putting the two concepts together and getting a
Bitcoin Twitter botnet?
