Every open source license will by definition allow packaging and selling the code or reposting it on a site with advertising, permitting to do that is one of the key freedoms; if you're forbidden to use the code for commercial purposes, then that's not an open source license. See https://opensource.org/osd https://opensource.org/osd MIT will allow that, Apache/BSD/Mozilla licenses will allow that, GPL and LGPL will allow that, Creative commons CC-BY and CC-BY-SA will allow that - the only difference is extra conditions e.g. GPL will require the seller/redistributor of the code to keep the same license, CC-BY will require leaving attribution to the author, etc, but all of them will allow someone else to redistribute the code for commercial purposes.
