What About Stop Signs?--veinglory

The recent discussion has made me think that perhaps red flags are not the most important issues in publishing. For a start some are clearly quite subjective, such as bad covers, POD fees and how/if owners should publish through their own press.
What is less debatable is the matter of stop signs. So perhaps it is more helpful to replace the current 'smoke' and 'not recommended' tags with 'flags' that specify what is being flagged, and 'stop signs' but again specifying the reason. In which case it makes sense to start with the stop signs as the more serious issues.
If I look at the current
list the 'not recommended' presses are
ABCD (reported non-payment),
LA Media (reported non-payment under a previous publisher name),
Ocean's Mist (confusion surrounding possible closure) and
Silk's Vault (reported non-payment).
So at this point the EREC stop signs seem to be:
1)
reported non-payment and
2)
high risk of closure/bankruptcy.
Based on this is it time to ease up on
Ocean's Mist which seems to have stayed open and kept on releasing books? Are there any other conditions that should be an absolute stop sign, before moving on to less serious issues?
