Hi,
I am an experienced software and Web developer, and I am highly expert at developing Web scrapers, crawlers, and bots. I understand that you want to scrape data from a forum (no login needed) so that you can eventually compare the scraped data with the present data on the website to determine which topics and messages have been deleted. Just so you know, I have already developed a plethora of Web bots, accessing websites such as Google (and its services), Facebook, Lenovo and a lot of other websites (some not globally popular), on which clients request me to develop bots. That's how confident I am that I can develop yours. I am a dedicated developer, and if you want to work with the best, you got to work with me.
By the way, I have worked with French people before, and they are very kind to work with.
Respectfully yours,
Mark
