Hello! I found this thread quite by accident ;)
The current implementation of structured tasks has several problems:
1. They are very easy to make, which allows users not to think what they are doing.
2. You can make a lot of them, partially solved by limits, but still it is impossible to reduce the limits forever.
3. There can be multiple added links in one edit, which does not make it easy to undo the wrong link.
4. There is no automatic/semi-automatic notification to a newbie that their edit has been reverted for such and such a reason.
To deal with these issues, you can do the following:
1. Create a module, but for experienced editors (500+ edits)
2. Instead of / together "add link" they will have "check link"
3. When checking, the editor gets already corrected articles, with added links.
4. He checks each link and if it is incorrect, he marks it and leaves a comment.
5. The comment is posted on the participant's talk page.
6. If there were many (60%) such reverts for one participant, then access to the tool is blocked for him.
It seems to me that this will solve problems with new editors as well and will attract experienced editors to review contributions.
