Without a doubt tho, IMO, it has something to do with the block size debate and is not an actual attack on BTC itself.
Somebody is trying to prove a point. At the moment they are proving that BTC can function fine with more tx's flowing thru the network, so bandwidth is not an argument
If you want a transaction processed, all you have to do is add at least the normal fee of .0001 and it should go thru fine.

From here you can see that there are 90k spam tx in Mempool backlog, and total fees of 4.5 BTC, giving an average fee of 0.00005. Given that genuine tx's will be being sent with minimum .0001, and many with more than that, the fees on the spam are tiny, hence the backlog should only affect anyone who wants a fee-free tx. Boo-hoo ...
Personally I think it's actually showing how robust the system is.
Thanks for the info, I haven't been following too closely but my transactions are going through as normal. As you said:
