Do you have any evidence for systematic underreporting? One could just as easily say that the members of control groups (who do not receive cash) would have a reason to underreport their spending on things that are not approved of in order to receive more potential money in the future. Also the research presented by GiveDirectly also includes studies of people where the cash is not from the same people as the surveys (for example state funded benefit programs that have clear and universal criteria unrelated to spending or consumption.) In those cases again there is reason to expect the underreporting to be similar across both groups that get cash and those that do not currently.

According to various RCTs, when their neighbours start getting money, women are less likely to report their husbands beating them. On the other hand, they're also less likely to report being satisfied with their life. There are [just about] plausible mechanisms for how spillover effects from donations could cause those behavioural/satisfaction changes amongst non-recipients in a neighbourhood, but recipients thought they were less likely to receive money if they reported domestic violence or said they were satisfied with their life is the most Ockham's-razor satisfying one. (It's also likely part of the reason why recipients seem surprisingly unlikely to report increased satisfaction from life after receiving life-changing sums despite positive changes in almost every measurable area.) Response biases are difficult enough to eliminate in social science surveys when participants have no reason to suspect a sum greater than their average annual income may hinge on their answers.
