On Friday afternoon in the U.S., am I permitted to click on a news site from Israel which I presume is maintained by Jews in Israel and continually updated by them, even on Shabbat (e.g., Jerusalem Post). Since it is already Shabbos for the Israel-based employees who are updating their website, am I inappropriately receiving benefit from a Jew’s work performed on Shabbos and thereby prohibited by “Maaseh Shabbos", benefitting from work that was done by a Jew on Shabbos if I read the articles which are newly posted after it is Shabbos in Israel? If this prohibition were to apply, then I can never look at those postings which originated on Shabbos.
It is forbidden to benefit from a melachah performed intentionally by a Jew on Shabbos itself - but immediately on Motze Shabbos, it is permitted (Sh"A Orach Chaim §318).
It would therefore be permitted to benefit from the melachah performed by the site after Shabbos.
[The Pri Megadim [A.A §325.22] posits that when the Melacha is performed by a yisroel mumar, it becomes forbidden forever. According to this, it is possible that in our case it would be forbidden even after Shabbos. See, however, Minchas Yitzchok Chelek 3, §78.]
What remains to be clarified is whether on Friday - before Motze Shabbos, but not technically bo bayom, it is permitted or not. Is the prohibition specifically on Shabbos, or is it simply assur until Motze Shabbos? [I would venture to say it is prohibited, but have no source offhand.]
