This is just my opinion but anyone can tag anyone for any reason they want even if it is against the advice of Theymos, but you will have to live with the results of your decisions.
You can tag Vod for "licking his boob" if you want but he and the court of public opinion will probably crush you and remove you from DT. Others may also tag you for leaving bullshit feedback.
I agree with this approach the most. At the end of the day it will always be somewhat subjective and should be left this way.
I also like the idea of coming up with general rules of thumb, if only so there is less chances of retaliatory feedback.
OK so here's my votes:
Extreme harassment - no, except in cases where physical threats or other illegal activity is threatened toward the user
Asking for a no collateral loan - yes, but only for Newbies
ANN bumping - no, but yes for the provision of ANN bumping services
Colluding - yes, evidence needs to be supplied ("proof" is even better)
Leaving fake negative ratings - yes, evidence needs to be supplied
Loan defaults - yes, especially if the loan recipient refuses to make/adhere to plans for repayment
Business activity that resulted in the loss of funds by others - yes, evidence needs to be supplied
All trust ratings (positive or negative) should be properly referenced going forward.
I also have a question: what about members supporting fake ICOs? ICOs that clearly have:
a. fake team members
b. plagiarized white papers
c. characteristics associated with Ponzis or MLMs (fixed ROIs and extra heavy emphasis on affiliate programs)
I'd like to get a general consensus on these items as well.
