Screen & freeze community entries.
Short, concise description of the idea
It should be possible for a community maintainer to "screen" an entry, thereby making it invisible and uneditable.
Full description of the idea
This is somewhat similar to this suggestion, but is not the same. Under that suggestion, a maintainer could "screen" a community entry until such time as its poster fixed it, at which point the maintainer could "unscreen" it; this was intended primarily to address malformed HTML in entries.
Under this suggestion, a maintainer could "screen" a community entry, at the same time preventing its poster from editing it. This would be useful if a maintainer wanted to report an entry to the LiveJournal Abuse Team; the maintainer wouldn't want the entry remaining in the community, and also wouldn't want its poster to notice that it's been screened (and suspect that it's been reported) and go edit or delete it.
An ordered list of benefits
Added anti-abuse measure.
Greater flexibility for community maintainers, so fewer will need to resort to the much-maligned community moderation.
The Abuse Team will get fewer reports that they just can't do anything about (since an entry, once deleted, cannot be used as evidence).
An ordered list of problems/issues involved
A maintainer might take advantage of this to freeze an entry whose poster hadn't meant to post it, or whose poster had meant to post it elsewhere. (True, the entry would be invisible, but the maintainer could later unscreen it without telling the poster.) This could cause embarrassment.
That's all I can think of. If you think of anything else, comment!
An organized list, or a few short paragraphs detailing suggestions for implementation
It could be combined with the above-mentioned suggestion. At the collective screen-entry page, there could be a checkbox, "Enable poster to edit entry."
If the poster is not allowed to edit the entry, then there's no point e-mailing him to inform him the entry has been screened.
If a community lists moderators - even if the community is unmoderated - then they would presumably be allowed to screen entries and to see screened entries. (See the discussion at the above-mentioned suggestion.)
Moderated communities need not be allowed to screen entries. (I could go either way on this.)
The screen-entry page might link to the Abuse FAQs, or to a few select of them.
