Thanks for the post Rachel! I admire you looking into the topic. 

However, one to add is that AMF monitors net usage uniquely stringently and this likely leads to far fewer people using the nets for fishing.  (or at least they did until 2015)

From a 2015 article:
However, AMF takes a number of steps to stop misuse. We believe that each of them has contributed to the success of our distributions.

1. Malaria education is key. We work closely with local health officials, the front line health teams and the village and community leaders, to ensure the community is fully aware of the connection between sleeping under intact nets and preventing malaria.
   
    
2. AMF uses extremely rigorous pre-distribution surveys to determine precise net needs, followed by independent checks when the nets are given out to ensure no nets are diverted away from households that need them.
   
    
3. AMF conducts post-distribution check-ups to ensure nets are being used as intended every 6-months during the 3 years following a distribution. People are informed that these checks will be made by random selection, and via unnannounced visits. This gives us a data-driven view of where the nets are and whether they are being used properly. We publish all the data we collect: example here. This type of follow up work is currently unique to AMF, although we hope the practice will become more widespread where it is feasible.

At AMF, the extensive data we have collected verifies that the number of nets we have distributed that are used for fishing is immaterial.

Given that AMF is the main bednet distributor that EAs give to (Malaria Consortium distributes medicine), I think the negative impact of EA-influenced bednet distribution is lower than one might assume from your post!

Would someone from CEA be able to comment on this incident?

'A third described an unsettling experience with an influential figure in EA whose role included picking out promising students and funneling them towards highly coveted jobs. After that leader arranged for her to be flown to the U.K. for a job interview, she recalls being surprised to discover that she was expected to stay in his home, not a hotel. When she arrived, she says, “he told me he needed to masturbate before seeing me.”'

Was this 'influential figure in EA' reported to Community Health, and if so, what were the consequences? 

[Caveat: Assuming this is an influential EA, not a figure who has influence in EA but wouldn't see themselves as part of the community.]

Thanks for sharing this! As someone who identifies as an EA, I feel that it's important to be familiar with a wide range of problems in the world, and this alerted me to a new one (and some amazing news!). 

Brother is used as a term of affection in a fair few languages (including Swedish), so I wouldn't just trust a tweet. 
The Swedish wikipedia article on Per, however, confirms more definitively that they are brothers: https://sv.wikipedia.org/wiki/Per_Shapiro
