Scraping someone's hard work then?

I'm developing a site which as a whole will contain a shitload of useful data, I can't wait until idiots start scraping it...

**justFred** · 11-21-2007, 05:36 PM

wow I definitely rolled my eyes at this one.

We have been testing one in a craigslist auto-poster, it's working good, but still needs a few tweaks.

**Sosa** · 11-22-2007, 03:00 PM

this isn't anything for stealing someones website work, spamming websites or anything like that. Simply filling in the captcha on one page after I make some selections by hand.

So, how many of you would buy a copy of a script that did that if it were made available?

Just wondering.

don't think we are all stupid.
either you post a link of where you want it or you go down as a spammer in this board's history.

actually thats not true , i put captcha's on my porn sites to keep the blind guys from cheating me out of my goods. , obviously he isnt blind so he might need it for that..

actually its a serious issue.. ( blind people and captcha's ) many sites now offer audio "captchas"

**StarkReality** · 11-27-2007, 01:32 AM

Depending on what you need the captchas entered for, you could go the visitor incentived way, too. Easy example: A proxy site that requires a captcha before the visitor can surf to the site of his choice...so you basically let others manually enter the captchas you need to be entered...

Maybe because it is none of your business and he doesn't need/want the competition for what he is doing.

Umm because why would I want 10 other people jumping and doing the same thing. A few people know about it, and I have already talked to them about the project.

For everyone that thinks this is spam, sorry but it isn't just like I have mentioned before.

**DBS.US** · 11-27-2007, 09:56 PM

It's about the competition baby
