I didn't get any SEM for week 5. Been in from the start of this round so got the first 4 payouts. Name is still on the list. Plz check. 
It might have everything to do with the fact that you posted on July 11th and then July 27th.
Nearly 2 weeks apart when the airdrop is for those who post at least once a week.
Also, the calculation is done by post count. So, if you posted, but a prior post you made is deleted, then it also appears that you haven't posted anything from one week to the next. Something else to consider if you're only posting one post a week.
Might be that I was skipped last time for missing a week in July. But I posted on 27th July and got paid week 4. Then posted on 4th Aug (still there) and didn't get paid week 5. No worries. Hopefully will get this week's.
