Spiderpunk

If a creature entering the battlefield has riot but can't have +1/+1 counters put on it, it gains haste.

If you choose for a creature with riot to gain haste, it gains haste indefinitely. It doesn't lose it as the turn ends or if another player gains control of it.

Riot is a replacement effect. Players can't respond to your choice of a +1/+1 counter or haste.

While Spider-Punk is on the battlefield, spells and abilities can still be the target of another spell or ability that would normally counter them, but they won't be countered as that spell or ability resolves.
