Hey Guest,
An update on the OFCOM situation: As you know, censorship around the world has been ramping up at an alarming pace. OFCOM, the UK’s communications regulator, has singled out our community, demanding compliance with their Online Safety Act despite our minimal UK presence. This is a blatant overreach, and they have been sending letters pressuring us to comply with their censorship agenda.
Our platform is already blocked by many UK ISPs, yet they continue their attempts to stifle free speech. Standing up to this kind of regulatory overreach requires lots of resources to maintain our infrastructure and fight back against these unjust demands. If you value our community and want to support us during this time, we would greatly appreciate any and all donations.

I'm sure there's a scientific reason but it just comes down to different biologies/evolution

They can't use humans to test the LD-50... so its really just an approximation, humans might die from lower doses.

LD stands for "Lethal Dose". In Toxicology the Median Lethal Dose is called the The LD50 , which is the amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 is one way to measure the short-term poisoning potential (acute toxicity) of a material.
Toxicologists can use many kinds of animals but most often testing is done with rats and mice. It is usually expressed as the amount of chemical administered (e.g., milligrams) per 100 grams (for smaller animals) or per kilogram (for bigger test subjects) of the body weight of the test animal.
That is true, but animal LD50 data can be applied to humans. So if we include specific safety factors in such calculations and allow for the variability between individuals and how they react to a chemical, and allow for the uncertainties of experiment test results we could come up with a fairly true LD50 for a human. Anything is possible in Science...says she the Scientist.
