It's not a stupid question, given the number of recent take downs.
It should be safe to assume that there is an ongoing campaign by Facebook/Instagram.
That means they most likely also contacted Followliker.
The big question is, what is different about Followliker in comparison to MassPlanner or Instagress that could make them a temporarily safe option.
Maybe a different jurisdiction that is out of reach of FB/IG, etc.?
To me it is a business decision:
Do I invest a large "A" amount of money with a "B"% chance of the software getting shutdown in the next "C" weeks to have a potential benefit of "D" for the remaining software "lifetime".
