    Scraping Telegram data, especially personal information like phone numbers, may violate Telegram's terms of service and privacy laws such as GDPR, exposing users to legal risks.
  • Risk of Account Bans
    Using automated scraping tools on Telegram can lead to accounts being flagged or banned by Telegram due to violation of platform policies against bulk data extraction and spam-like behavior.

Analysis

Mastros.online
ShellNewHandler

Overall verdict

  • I don't have verified, up-to-date information about Mastros.online, so I can't confirm its legitimacy, quality, or trustworthiness. I'd recommend researching independently before using it.

Why this product is good

  • I don't have reliable data on this specific site's reputation, ownership, or service quality
  • No verified user reviews or trust signals are available to me for this domain
  • Unfamiliar or niche domains can carry higher risk, so caution is warranted
  • Checking third-party review sites, WHOIS data, and user feedback would give more accurate insight

Recommended for

  • Users willing to conduct their own due diligence before engaging with the site
  • Shoppers who check for SSL security, clear contact info, and return policies before purchasing
  • Anyone who cross-references reviews on platforms like Trustpilot, Reddit, or the BBB before trusting a new site

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
