The #BTS "Army" are mad because #LastFM banned 'bots' as they were scrobbling BTS 24x7 on multiple device balooning the number.
One user signed up in 2023 and had nearly 900,000 scrobbles which all of it was BTS.
Their feed showed that songs were replayed or played on multiple device…

Climate alarm!
This is NOT within normal bounds for the Netherlands: the second half of June is now forecasted to become the warmest in 126 years, beating June 2023 by a margin of over 3°C!
24-hour average of 23.4°C, in this forecast.

Abstract: A method for measuring the altitude and particle size of noctilucent clouds, based on positioning and photometry from wide-angle three-color cameras, has been developed to determine the three velocity components, particle radius, and its derivative with respect to time for different cloud fragments. The updated method is applied to observational data of bright clouds during the summers of 2023-2025. Meridional motion of the cloud is found to be the principal factor driving the change in particle size. The effect of particle size evolution in the presence of a strong latitudinal temperature gradient is also studied.

SpaceX's draft IPO filing: from 2023 to 2025, Starlink's individual subscribers rose from 2.3M to 8.9M, revenue grew from $3.9B to $11.4B, and ARPU fell 18% (The Information)

SpaceX’s Starlink Revenue Per User Fell 18% As Customers Quadrupled
SpaceX’s Starlink satellite internet service quadrupled its individual subscribers between 2023 and 2025—but the average revenue each subscriber brought in fell 18% to $81 a month in that period, a draft version of SpaceX’s initial public offering prospectus shows. The decline in Starlink’s ARPU ...

Just did very approximate calculations; with 10g of lithium per drone*, and assuming the Russian and Ukrainian drone efforts consume 5m units a year**, that'd be ~50 tons of lithium deposited into the environment per year, mostly within, let's say, 50km of the grey zone***. It's only about $20,000 / ton****, which means $1m of metal*****.
So to answer my own silly question: no, it won't be economically viable to scalp the top few inches of topsoil and extract the lithium from it.
* Roughly right for quadcopters / small FPV; larger and longer range ones will have more, so this is a bottom bound. (OTOH longer range UAVs will tend to use ICE kerosene rather than batteries
** Changing all the time as both sides try expanding production as fast as they can manage. Ua are scaling much faster at time of writing
*** Handwaving. Contact zone's hardly moved since early 2023; OTOH Ua are pushing range limits on small battery-powered form factor, saw a 60km claim for the Logistics Lockdown operation the other day
**** There was a big spike to the $70-8000 range in 2022; median price is closer to $10k than $20k
***** (IDK the chemistry but presumably it's in an exciting range of different compounds, depending on how many bits the battery was blown into, how hot / pressured the blast wave was a few tens of mm from the boom, what other stuff was in the vicinity that the lithium would combine with, etc etc.
