We don't recommend running Like4Like from multiple devices simultaneously.
This will increase your chances of earning likes but at the same time your account
will end up doing much more activity. A lot of activity coming from multiple devices
may result in Instagram considering your actions as spam and restricting you from
liking any more posts for several hours. There are no consequences for getting these
restrictions, you will not get penalized further
but this may result in you getting less likes in total.
What we can recommend doing instead is this. If you haven't earned any likes on one
of your devices for a minimum of 12 hours, you can try switching devices. Just make sure that
only one of these devices has the "Activity switch" turned on so that their activity doesn't overlap.
