The contract at IXPs almost universally includes a phrase like "will not engage in fraudulent announcement of routes", but proving that happened to the satisfaction of a non-profit's board of directors is difficult. You really have to have completely collinear anatidae.
I'm stealing this phrase, please and thank you.
> sounds incredibly pretentious. I think most people would appreciate Plain English [0].
I can't speak for most people, but I didn't know what it meant, learned it after reading it, and found it quite appropriately funny and witty. I also learned a new word. There was nothing I found pretentious about it.
I think a helpful and reasonably objective criterion in deciding this might be whether the use of the phrase was (1) necessary to send the correct message, (2) required to understand the received message, and (3) liable to send an incorrect message. If #1 = no and #2 = yes, or if #3 = yes, then you should probably avoid using it. In this case it's #1 = no and #2 = no and #3 = no, so it's fine.
I'm not sure what to do improve the situation, but there definitely seems like a need for improvement.
