Laszlo doesn't use twitter, reddit or any other social media. Any message coming from that is 100% a scam.
Here's what he said about this:
I don't do social media, the people pretending to be me on twitter/reddit/etc begging for donations are scammers. -Laszlo

This is also a good opportunity for newbies to learn about how to verify a signature to prove someone is who he is claiming to be. In the previous message there's a Bitcoin address associated with laszlo, a message, and a signature. Anyone can verify that message with that signature, and see if it's valid. That means that the person writing that message has control of that Bitcoin address.
So, in this case, you have the address of the 10k BTC pizza transaction in the message, and you can check that the transaction actually occurred in the blockchain at that time:

Tools->Sign/Verify Message and then input the following:
message: I don't do social media, the people pretending to be me on twitter/reddit/etc begging for donations are scammers. -Laszlo
signature: HCEMyDqAXNBcpPbgQjYsm1V+HReQBWfBvNWr14iNBQj0b2u4mkgBl4S00gv1hXZUZQRaICKBRIxaxeeUNHQx94Y=
address: 1XPTgDRhN8RFnzniWCddobD9iKZatrvH4
If you click
Verify, you'll see if the signature is valid or not.
That way you can 100% know that the person who wrote that message has control of that address.
