3. Express an opinion about the project, ask questions.
Item number 3. It depends on the nature of the content. If there is no spam, plagiarism, deception, this is not a violation. They can be project participants, testing it and asking questions. I can not be sure of this and can not prove otherwise.
This looks like a clear cut paid shill pumping services from random accounts for random ICOs. It is also shown clearly from the quoted messages above, presenting it as an testing system or something like asking questions does not look acceptable IMO.
Still its your own choice of giving neg trust for it, but atleast you should have not protected a clear cut spam promoter smartman.
After reading some comments from Theymos, I think his views are good guidelines in using the trust system and I can see he is on an total opposition of giving neg feedbacks for spamming. And your arguments too look correct after looking at the moto of the new trust system explained by him.
I too think much clerification is needed for leavings trust ratings on such stuff.
We have 100s of other DT members so bring this into their attention by creating a thread in
Reputation which might get more healthy discussion.
This looks like a great advice for you @KTChampions or just move this topic there if possible.
