Full disclosure least i be accused of bias or having an agenda, I had a very regrettable experience and horrible result.
But putting that aside, because I have for the most part moved on, are you genuinely trying to suggest there isn't at least some sort of coordinated marketing going on? Seems be a bit of a timely influx of older results including like previously mentioned, 2 people making multiple posts, and at least one or two bumped results. Just seems pretty coincidental to me, but more coordinated.
But not that there's anything inherently wrong with that though. NOTHING wrong with people sharing good results or results they're happy with! God knows I wish I could have. I think the issue is probably more with transparency than anything else.
OP While I do see some decent work, esp with Indian patients, and I'm not suggesting you away from any clinic at, I would suggest that you don't limited yourself to India or one area. At the very least get online consults from many and see what they say. My biggest problem was (being naive) seeing a few decent results from an inexpensive clinic and going ok yep that's it. And the only other research was asking that doctor. So, India might be the best place for you, and the advantage of being in India and close to several clinics is that you can visit several of them and talk to the surgeons etc in person. But it wont hurt do expand and get some opinions frlm all over the world.
