American, I’m referring to rav yaakov shapiro, who was among the only talmidei chachamim online in the late 90s and early 2000s. Both ujm and i are into his writings, with him often quoting him word for word. Rav shapiro is also the author of the encyclopedic the empty wagon – you can reach him by email, which is in the sefer, or on his podcasts online.
The rest of the essays are on the frumteens archives, some of which are on old blogs and others are on jewswithquestions, a short lived update to frumteens.
Rav Shapiro is very close to rav elya ber, who guided him in frumteens and his other activities, including his anti-Zionist writings and protests.
