Thanks, added both with preliminary assessment.
For POW88 :
pow88.com             1+2                => 2/7 = Probably legit (preliminary assessment)

I didnt give them a point for referral because its only 1%. PIctures dont look impressive, but neither does the available hashrate (50TH), this is a small operation.

Cloudmining.sg doesnt look that good so far:
cloudmining.sg        1+2+3+4+7          => 5/7 = (very) suspicious (preliminary assessment)

And ive been generous granting them point 6 (identity) despite the fact there isnt even a contact address on their site, but I guess this will do:
