Why some signals would disappear?

[bergen288]

There a few times that my interested signals disappeared in a couple of days.  They are MT4 signals.  What's the reason?

Thanks.

They usually fail and get deleted by their owners or rarely turn to private signals.

based on my experience there are 2 possibilities:

1. the owner (by whatever reason) delete the signal or change it as private signal so that it will not be visible by public

2. There's an issue with the signal (no activity, high drawdown, etc) so the system automatically hide / delete the signal
