    Looks like another linkedin scraper signalhire.com page has already been removed, it was working a few hours ago. Source: over 1 year ago
  • Forward spam emails back to sender!
    I just found a few data collator sites, zoominfo.com and signalhire.com are just two - they seem to scrape sites like Linkedin etc and collate everything. Personal numbers can be found pretty easily, if you've ever signed up for a business identification number it could be there, could be in a data leak somewhere - these companies are pretty shady and will buy data from places to just get a lead.

  • Personal LinkedIn Data Sourced and Shared
    Not to mention bunch of scammy crawlers like signalhire.com that constantly scrap LinkedIn data and make it fully public. Source: almost 3 years ago

  • A responsibe layout with a single breakpoint - how to replicate ?
    Just wondering if you could help me. Spotted this website https://upstackhq.com/ which is awesome as it is perfectly responsive at every viewport width and has only one breakpoint. Every element actually has a variable width or font-size or anything to size it, that is not fixed. This gives a really smooth feeling to it. No "jump" in layout such as with a classic responsive page with breakpoints. Source: 8 months ago
