getting spammed on bugzilla

[Joel Brobecker <brobecker@adacore.com>]

Hello,

Our bugzilla instance is being used as a spamming platform.
Spammers do so by just posting answers to random PRs.

As a result of this:

   - The PRs gets polluted with these annoying messages that
     we cannot remove (just mark as spam, which is a game of
     wack-a-mole and personally a waste of our precious time);

   - People on the Cc: list get emails about them.

     I wouldn't be exagerating if I said that 95% of emails I am
     getting from bugzilla, at the moment, is spam.

I think the problem is that spammers can create their account
without any form of validation.

Is there something we could do about this?

Pedro tells us that:

I'm happy to help with answering those legitimate account
creations, if that makes a differnce.

Any other ideas, perhaps?

Thank you!
