While attempting to find information on, of all things, nginx http2:

Sorry, your request can not be served. For security reasons, it was blocked and logged.

If you think that was a mistake, please contact the webmaster and enclose the following incident ID:

[ #2773066 ]

These ninjas are so fast, they block you before you even do anything malicious! They’ve moved up from cutting you five times before you hit the ground into pre-crime heuristics.

Even if this false positive error included contact details, me thinks it’ll be easier to just source this information elsewhere.
