If other players did a "hostage situation" then that's not breakfastburrito_007 doing that. I am aware that there is a conflict about whether proGUI is considered cheating. What I have perceived has been political action around that issue, public logical argument attempting to convince others to support an opinion, and perhaps organizing of people to take action such as by establishing a voluntary rule on a per-hoster basis about use of performance-enhancing mods. That's different from a hostage situation based on lies.
I don't know how you can say this. The lobby terms of use say that defamation is not allowed. Defamation is "false or unjustified injury of the good reputation of another, as by slander or libel". It involves telling a series of lies or spreading rumors. An example is when Geriatrix lied about why ValihrAnt wasn't playing 0ad as much in June.
The lobby terms of use say that threatening is not allowed. A threat is "a declaration of an intention or determination to inflict punishment, injury, etc., in retaliation for, or conditionally upon, some action or course." An example is when Geriatrix threatened to leave a team game if leopard wasn't banned. He later threatened to leave a team game if breakfastburrito_007 wasn't banned.
The lobby terms of use also say that pejorative terms are not allowed. A pejorative is "disparaging, derogatory, or belittling, such as bean counter for an accountant". Examples are when Geriatrix called op players 1200, meaning 1200 rated, in public lobby chat several times over the last year, and called leopard p*ssy. The word is censored by the forum, but it's visible if one reads mainlog.html directly.
Sources of definitions: defamation, threat, pejorative.
I want people to speak the timeless truth, regardless of current friendships or conflicts.
I guess that because you didn't answer the question directly, and you didn't make a statement at the time that you started your break from 0ad, that you didn't stop playing 0ad because of breakfastburrito_007.
