I don't think identifying uploaders to "porn platforms" is a good idea. Some reasons why:
1) I don't think their ideas make a distinction between real and fictional content. If that was put in place, it would create a pointless burden.
2) "porn platforms" are often not used just for "porn".
3) Safety?
4) Likely triggered by moral panic / misrepresentations?
Only part of the Parliament though.
Noting that for "child porn", the Canadian Police took a look at reports from the website "Pornhub" and found that 90% of those sent by the platform were without merit.
There is also a possibility that they themselves are inflating these numbers because it is *Canada* after all. The actual numbers could be even lower.
According to a frivolous lawsuit from a religious group (which will probably get dismissed), the platform removed the content promptly, upon knowing of such content.
If you think about it, the amount of such content probably adds up to a mere few attempts per day.
Not every "porn platform" is Pornhub. Pornhub is very corporate and very big.
It's also not European, it's Canadian (duh), therefore any measure made here is irrelevant (although, Canadian authoritarianism would be problematic in it's own right).
Nor is there usually a distinction between giant and small. Again, kind of burdensome.
Of course, I don't know what the particular basis for this is, however, if that is it, it would seem pretty weak.
Even with a stronger basis than this, it would not be particularly proportionate (or helpful).
In any case, arguments tend to be fairly speculative and unsubstantiated. That doesn't bode well for the proposition of any particular measure.
