Hi, psychtoaster
Welcome to the forum. Unfortunately here we don't allow substance IDing threads. It's important you realize that you cannot properly ID blotters just by the design and that it can be dangerous to assume that you do know for sure.
There are region forums including one (EADD) for europe, and different drugs like MDMA or LSD are discussed there including batches. I can't really speak for EADD or comment on their policy all that much, but you are not to really try and ID i would say.
I can move this thread over there for you if you want. Sorry of this is a bit unclear about the rules. They would have to merge this thread into their LSD thread, you can discuss LSD in europe there if you are just generally interested in talking about it.
QED
