Genuinely asking, not trying to start anything.
Three new sellers appeared in the last six weeks with suspiciously similar site templates.
Between payment processors dropping vendors and customs getting stricter, the whole thing feels less stable than it did a year ago.
Will update this post if I learn anything useful.
