In the recent days I have noticed suspicious activity in my account probably due to some apps I had added in my account. There were autolikes and automatic follows appearing in my account. So I checked my account , undid all the automated actions and checked my privacy settings to see which apps had access and I removed almost all except the ones which are highly trusted and I use regularly.
However yesterday morning an extremely vulgar spam link was posted from my account which was seen by people at my work. I informed everyone that I hadn't posted it , deleted it and as an immediate measure I have deactivated my account.
I am afraid such things may happen again when I reactivate my account as I have already checked which apps have access to my account . I need assistance in ensuring that such activities are not repeated in my account. Kindly guide me on what steps I can take to ensure safety of my account.
