Better to search for an alternative than to just swallow whatever the authorities are shoving in our throats. If you lose one opportunity, you must seek another. Time and tide waits for none. I think this forum is much more suitable to advertise mixer services than other forums out there. Seems a bit non-active forum but with this move, I think this forum will also gain popularity. And as long as those mixer services are not into some shady business, they are all good.
Always remember that mixing services is not illegal. But bad people will use it for criminal purposes. If those services can somehow prevent this form happening, they can stay here as long as they want.
