Not saying these are necessarily all yours but the cluster of accounts O__________O, billme, saycheese, wonderous, endlessly, nxzero, v2hle0thslzrav2 are all in each others top 5 or so which is usually a sign of a good match and unless you are saying that you never revealed any identifying info in any of the several hundred comments you have made there is likely some loss of anonymity. If you used a VPN consistently on one account but didn't on one of your earlier accounts then the whole point of the VPN goes right out the window if someone say gets a subpoena.

One of the advantages to being anonymous all the time is nothing is tied to an identity; not an IP address, not a physical address, etc.
