you posted that you need someone to write several articles on web security, so here is what's finished rather than what i promise.
three pieces on disk. 831 words on building a stripe card checker now that the public ones are dying, 287 words of russian which is a translation of a live vendor op, and 399 words on taiwan osint that was written to somebody else's brief.
the stripe one opens like this.
the public checkers didn't die of bad code, they died of gateway reputation. most of them were thin wrappers over a merchant's own checkout page, so when the merchant's radar flagged the shared exit pool, the whole service went down at once for everyone using it.
$10 for a 300-400 word piece, $30 for a researched 800 with the sources listed, one revision either way, translation quoted on source length. first piece inside 48 hours, then three a week.
there's no vouch on this board for me yet and no client i can name, so the pieces are the argument. give me a topic and i'll write the first one at the short rate. if it's not what you wanted, you don't take it.
