Vulnerablecode useragent

Much of what we're doing now is scraping the webpages for the required information. Doing such activity without even declaring who we are might not be seen as a very good practice.
We need to settle on a useragent choice. Some websites even block regular scraper useragents. There are two solutions I can think of:

- One consistent and custom useragent
- A list of browser user agents

There could exist benefit of either methods but I'm not so sure.
