Hello, I noticed the same issues recently. All along the week, as the media coverage increased, the way that the projects and tasks were completing themselves changed. From large tiles completed by several users turn by turn, we came to big tiles directly divided into tiny tasks, being completed by only one user in a few minutes. The peer review process, making the quality of the work, was botched. I personnaly found many tasks checked green as "validated" by newcomers, and "completed" by newcomers.
For example, here is an extract from a message I sent to Dale Kunce (admin of many Haïti projects), where I was pointing to the fact that many newcomers did not see the instructions tab and so did not use the new Digital Globe imagery, and stayed using Bing (that was before today's post disaster imagery). But I unfortunately received no answer. I am not here to complain about that: I understand that there may be a lot of other things to do during these days. > I just saw 4 tiles on the #2223 - Hurricane Matthew: Grand Anse coast > project and all were wrong according to me (but maybe I am wrong and > somebody have to tell me): - task #53 was checked "complete" by > @michaelcraven, but many buildings were missing. - and the 3 main tasks of > ANSE D'HAINAULT town : #232, #233 and #13.
