Great you did this Validation. As announced in the last thread we had on
the Validation topic: I started a wikipage about Validation. May be good to
work collectively on it then move it to LearnOSM?

I use to send ad hoc messages to mostly beginner mappers, when their
mapping could be improved (most of time it is about squaring buildings,
creating easily perfect circles or not mapping blocks but buildings

I also find from time to time some squares that are neither empty nor close
to be and invalidate them

I think receiving messages (validation or invalidation) from the task you
mark as done has been ticketed for future implementation or discussed

I hope not, considering the number of jobs I recently created :)

IMHO I would say we do not need to be too restrictive if beginners do not
validate. The new capacity of visually checking who did what in the TM job
is a real benefit to have a quick control. Creating kind of admin
validators takes time for developers, complicates the process for becoming
a validator and therefore will potentially reduce the number of validators.
I prefer having in mind a list of OSM users I trust and discovering from
time to time new good ones or advising others who did not check all the
validation points. For sure every TM job should link to a shared, document
agreed by the community (the one I just published being just a first draft)
