Much like User:Moneytrees/2010 CCI sort, giving a short breakdown on the oldest CCIs for coordination purposes.

2011

edit
Copied from Websites, mostly foreign
Blocked
Difficulty: Hardest remaining. Over 1,000 articles to go through with primarily non-english sources at that. While the sites can be translated and copyvio can still be found that way, it's a lot of work for each one.
Pdel? Yes. Indef blocked, offline/translated sources, would be almost impossible to fully determine whether a violation or not.
Copied from Websites, books
Blocked
Difficulty: Hard. User showed a disregard for copyright, and he had no problem copying offline and online sources. Luckily there aren't too many large ones to deal with on this one
Pdel? Yes. Indef blocked, a lot of confirmed copyvio in print sources.
Copied from Websites
Blocked
Difficulty: Hard. Another large CCI with some large articles, but thankfully one that is well-sourced, so we know where the violations will be coming from.
Pdel? No, online sources so can be checked as normal and the vios seem pretty obvious.
Copied from Websites, books
Blocked
Difficulty: Very hard. Used offline sources primarily, and fairly large additions. They also literally violated copyright on copyright (probably, 71 diffs to go through to know for sure).
Pdel? Yes. Indef blocked, offline sources of questionable reliability.
Copied from Websites, books
Not blocked, unsure of contribs since.
Difficulty: Very hard. The articles that are left not only use offline sources, but the diffs are massive (almost half are +5000).
Pdel? Kind of. I'm luckily able to access some of the print sources and am trying not to pdel, but it may be a necessity in some cases.
Copied from Websites, newspapers
Blocked
Difficulty: Very hard. This is a weird one because the user referenced everything, but many of the refs are behind a paywall. The good news is that he quoted stuff in the references. The bad news is that's the problem. The quotes are often longer than the articles and that's the main thing that needs removal (unless the source is PD). Why very hard then? There's over 4,000 articles and most of them are large quote additions.
Pdel? Kind of. Since most of the edits are the "quote=" garbage it's easiest to just remove it at this point rather than trying to figure out if it's too much. The handful of prose additions that do exist just check how you normally would.

Difficulty:
Pdel?  N, usually well sourced and from web sources. Lower rate of vio than accepted for PDEL from this type of CCI.

Copied from Websites
Blocked
Difficulty: Very hard. Lots of articles and lots of sockpuppets
Pdel? Yes. Indef blocked and large numbers of sockpuppets to go with questionable sourcing.
Copied from within wikipedia (mostly improper merges and splits)
Not Blocked, edits appear ok since
Difficulty: Medium. Relatively small CCI and more a matter of attributing the edits, many of which are long gone due to the subject matter.
Pdel? No per above

Copied from foreign books, foreign websites
Not Blocked, contribs appear ok since
Difficulty: Medium-hard. Small number of article and diff size is small. What keeps this from being easy is the volume of foreign sources and translations
Pdel? No. Not much content left and what is can be found easily these days.

Difficulty:
Pdel? Yes, especially for deadlinks or unsourced. Stuff that looks like it's unattributed translations or an LOC dump probably shouldn't.
Copied from journals
Not Blocked, not significantly active since CCI opened.
