Here are some reasons that a blacklist is not a solution to the problem:
- It does nothing for games that are already in progress. For such games, the players (DM included) are, at best, simply encouraged to kick offending players, without offering any solution for the stalled game and potentially worsening it in the search for replacements (or ending entirely).
- The presence of a blacklist encourages the community to be more hostile and unforgiving to its members. Newer members may be scared off from joining, and existing members may be pushed out.
- New players who stall games will still do so, as the blacklist cannot recognize bad players until they have shown themselves to be so.
- Maintaining a blacklist is, in itself, a significant task requiring significant community buy-in to identify the offending members and non-trivial oversight to avoid false positives.
- Consistent PBP offenders will already generate a reputation as such due to the social nature of PBP games and this board's community, thus implicitly being identified as "blacklisted" without the need for an explicit blacklist.
- Most people who go long periods of time without posting do so due to changes in their life. It's far more likely to be a matter of lifestyle changes that were not foreseen 3-6 months prior than it is dickishness. In my experience, people in that situation tend to withdraw from PBPs, not apply to more of them. They don't need a blacklist to keep them away, they have real life for that.
- A blacklist would take a fair bit of time to fill with any useful amount of names, maybe more. It then doesn't even do anything for some time further until said blacklisted individuals would want to join a PBP game. It could be a year or more, easily, before the blacklist even has any positive impact, if it has any at all.
ShadowViper, you have yet to prove that your blacklist idea will produce any positive impact. Meanwhile, it has significant potential for negative impact. Before pressing further, you should reevaluate your position, examine what your idea hopes to achieve and how it will do so, and whether that is actually likely, and whether it is worth the potential consequences and collateral damage.
