The only ones blocked on there are shills or practitioners actively pushing high volume silicone.
That's what Loria uses. Literally talking to a guy elsewhere experiencing serious issues likely stemming from silicone. It's just not compatible with the body and there's a reason it was only sought out for approval in micro drops for retinal use. Your body cannot deal with it, it cannot fight an infection if one develops, it's just a ticking time bomb. PMMA has its own issues but it is completry different in every single way. It's not a volume filler. The spheres are inert and bio compatible. Yes you can get lumps, bumps, uneveness, lots of minor issues but they're not in the same realm of complexity as a bad reaction to silicone.
There's guys on only fans even who have gone to Loria, had a nightmare, and never talk about it publicly. I don't know if he makes you sign off on something or threatens to sue or whatever when people have a bad experience but they're definitely out there. Any legitimate cosmetic practitioner would look at high volume silicone injections as insane. Unless you're a hair restoration guy I suppose.
Save up your money and stick with products that are relatively safe and proven and easier to deal with if a problem arises. Or don't and good luck
