What my handle has been mistaken for on Twitter

I have the same handle here as I do on Twitter. (Call me an early adopter.) Too many people use the @ instead of a hashtag and name-check me instead of who they really intended. For the record, I am an American living in the state of Indiana, and these are my initials. I am not:
  1. SyCip Gorres Velayo & Co., the largest professional services firm in the Philippines, now a subsidiary of Ernst & Young
  2. The San Gabriel Valley in Southern California
  3. Syndicat Général des vignerons de la Champagne, the French union of growers of champagne grapes
  4. Schweizerischer Gewerbeverband, the Swiss Business Federation
  5. Sadhguru Jaggi Vasudev, an Indian yogi and mystic from Karnataka state (this one is kind of a stretch — G for "guru")
  6. SGV Gás, a manufacturer of "innovative equipment" for compressed natural gas in Argentina
