More information here. Worth bearing in mind that the two principal protagonists of this bad proposal are British Conservatives, Malcolm Harbour and Syed Kamall.
I have a certain amount of contact with MEPs, but perhaps not surprisingly very few of those who I know at all well seem to be directly involved with this.
Edited to add: Bart Staes, the sole MEP of the Flemish party Groen!, tells me that the Green/European Free Alliance group will vote against. Worth writing to them anyway to stiffen their resolve. More updates as I get responses.
ETA 2: Heide Rühle, the Green/EFA rapporteur, gives a somewhat different spin - she tells me that "most of [the rumours] are unjustified see my added explanation [which she attached, and I must say didn't make a lot of sense to me]. But we’ll meet once more with the legal service on Monday to clarify that no wording can endanger the freedom of Internet."
