Fake testimonials. So other stuff might be fake too.
Spams random subreddits to promote their website. Was rude to a user that commented.
In one of the advice subs they posted it was pointed out how obviously AI generated their testimonials were. The company didn't deny this, just thanked them for the advice. It's also quite clear how fake they are looking at the testimonials.
First two are people with very different names but almost identical stories of how helpful the company was helping them choose items for their 'dachshund'. Even if it's unlikely both had the same type of dog (sites only existed a month), it's weird they talk like they have been helped around a physical store by a helpful assistant, when it's an online store.
The forth testimonial is the biggest red flag. Not because of the weird rambling of how much the "customer" loves and admires and loves the site. But because they refer to the site as "Petsshop" not "Lirynpet", because obviously the AI was just told to come up with some fake reviews for a pet shop.
Again, they didn't deny these were fake or generated by AI. So there is no benefit of the doubt.
Not saying it's not a legitimate store, but seem very untrustworthy. They are willing to lie, posts spam and seems unpleasent.
