Makes sense. For this reason I used and tested the service myself a few times mixing my own sats. Also for this reason I didn’t rush to withdraw all my weekly signature gains. I left those in the “mining campaign”, and not only for the 12%, but just because I wanted to “believe” in the service I was advertising.
I tend to believe in the services I advertise, this is my rule. Even if I think signature wearer have by no mean any responsibility if the advertised service turns out to be fraudulent.
To some point, I believe, one just needs to test the service of what they are advitizing, even if it's not made compulsory out of their own will, as it will go a long way at least if a question is being raised upon the project on one's signature, the person can be able to explain properly if it works.
I was a victim of such a case where, when I was part of the campaign on the Full-member rank, I tumbled upon a thread that was talking about Mixers. When I dropped my explanation based on what I believed it was, I was corrected by a member of the forum, and the statement ended with "It even know about what you are advertising." That was when I took it upon myself to test the service myself to know how things worked.
This was before the 12% APR was added as part of the feature, and lucky for me, I don't have any funds in there. as the aim of using it was just to test the service mixing and withdrawal procedures.
