Will Tumbler.io have a solution to circumvent a looming mixer ban?
Tumbler.io doesn't seem shady like Sinbad.io, a proven shady darkweb mixer.
Google search provided many shady results for Sinbad.io but for Tumbler.io, search results seem to be legit.

To begin with, you have to accept that businesses are not created with the purpose of running bounty campaigns on the Bitcointalk forum. Only a small part of the crypto business presented itself here, which is a confirmation that it is possible to do business even without a signature campaign. So it is not mandatory to make a plan to avoid the ban and the whole business adapts exclusively to the Bitcointalk forum.
As far as I can see, Tumbler has started promoting on other platforms, which is part of the strategy that excludes activities on this forum.

Can you please clarify about your sudden decision of ending your advertisement 2 weeks earlier than scheduled dead line? What I'm trying to understand, was it your decision or the ad manager's? Because there was no need to pack and leave after only a few criticisms about an article you posted, you could simply either remove the article or just add a disclaimer that you are not supporting any particular country or company.

Moreover, what you did just added more to our "suspicion", it's like when you grab the stick, the thief runs. I hope you understand there is no hostility towards any Bitcoin service providers unless they are proven to be illegal by international standards, like sin bad became a hostile Bitcoin service provider the moment it was seized.  So if we are posting here, it's not because we are your enemies, we just need transparency that's all.
