ldeawhile searching for some topic we found many post related to "Banned/Block" user who are no longer part of this forum, and deleting the banned user data/record will save a lot of space and also reduce the record per search term. This will also there will be fewer record in the Database and the query will be expected fast.
1. Even if a user is banned, some of their posts are deemed valuable or helpful to other member.
2. Rather than deleting old data, i have better idea which are switching to faster hardware and hire Database Engineer to perform various optimization.
