Most of the local boards have dedicated moderators who evaluate published posts and delete those ones that have the vicious style and/or dull/irrelevant content.
For instance, Russian board has two high-skilled mods who perfectly cope with their duties including that ones which are relevant to improving posting quality .
To be honest, the campaign may not apply to every local board. As you mentioned, some local boards, like the German one, have active moderators who manage and clean up posts effectively. However, this isn't the case for all local boards. Take my local board, for example. Since we got the Naija Localboard in 2022, more Nigerians have joined, leading to an increase in both active members and low-quality posts.
Many members have discussed ways to reduce these posts and even reported them to global moderators, but without much success. We had taught of having our own moderator and an off-topic board to tackle the issue, but nothing has been granted. Additionally, quality posts often go unnoticed due to limited merit allocation to the only merit source we have @brainboss.
Despite the challenges, this campaign is relevant to our local board and many others, as a constant reminder. This campaign could help improve post quality on BitcoinTalk, even in boards with sufficient moderators. It may be of interest to such moderators to know that it's members are of good quality posting and probably reducing the amount of work they are to do as a localboard moderator.
