Is x16rv2 algo still work for ravencoin?

We figured out that mining pool software has two open ports. One is for kawpow algo to connect gpus. Another one works for x16rv2, and we were able to connect rasp pi to it via cpu miner. It has about 16 khs. The question is, are those x16rv2 shares are still valid? Blockchain gives them and accept them too, but it seems little weird.
