I assume that my posts are deleted when I delete my Facebook account, but what about the likes I gave to other posts? Is the likes count on that post/page reduced?Or the comments I made on other posts? Are they deleted?And what happens to the conversations I had in the chat? Do they still appear to the people I chatted with?
What happens to my comments, likes, and chat, when I delete my Facebook profile?
facebook;delete
You actually deactivate it, and once you do that all your comments, likes, shares, post and everything associated with your profile disappears like it never existed. But your message conversation will still be visible on your friend's inbox just there won't be your profile picture and link to it. If you reactivate the account in future all your likes, comments etc. will reappear.Update: If you choose to permanently delete your Facebook profile, the same thing happens plus all your data from facebook servers will be erased permanently, so there's no way you can regain access to your account as well as the data associated with it.If you want you can download all your data from Facebook before deleting the account. Goto your account settings  https://www.facebook.com/settings and click on the link that says Download a copy of your Facebook data and download the archive.
