Protect Ask against spam

[Regina Henschel]

Hi all,

can the ESC please discuss methods to protect Ask against spam? [And of 
cause establish a solution, or suggest a solution to the board.]

Read e.g. 
https://ask.libreoffice.org/en/question/106719/spam-why-doesnt-someone-from-tdf-post-their-view/
https://ask.libreoffice.org/en/question/103981/anti-spam-measures/

My personal favorites would be to block a user automatically after two 
of his posts have been deleted, or to block a user, after he had made 
two posts within a short time (2 min e.g.).

Kind regards
Regina
