Dear @Duome Team or @duome,
recently you announced the following:
As a precautionary to keep the forum's content from being compromised, we've initiated a one-week allowance for editing from the time of any initial submission. During this one-week window, members can make adjustments to their posts, but they will be locked from editing thereafter.
...
There are other forums and some social media platforms that also exercise this practice, some with a shorter time-frame to edit.
In other forums, there are also a lot of another options, like the following:
For instance, if a user is banned or kicked out, this information should be displayed under his avatar. That would be only fair! So one can know, why this user is not posting anymore. Otherwise it would look like a kind of extra punishment or something.
