All of the above.

Haye is the weakest paper champion in boxing. The WBA belt belongs to Wlad.

Wlad destroyed the REAL WBA Heavyweight Champ Undefeated Ruslan Chagaev, who clearly beat Prime Valuev in impressive fashion.

Wlad is the rightful WBA Heavyweight Champ.

This is true.

The other belt, WBC, was won by a Peter Wlad bested in an IBF eliminator before Byrd II while the current WBC titlist, Vit, was out of the game.

There is one real Heavyweight champion. Wlad. All other claimants are paper.

[P4P Opinion]

Each and every one of them. There are five World champions: Wladimir Klitschko, Jean Pascal, Sergio Martinez, Pongsaklek Wonjongkam and Giovani Segura.
