WTF?  No, there has been no forks relating to any of the antispam features.  Most of the antispam features are built into Bitcoin Core, which reject most possible valid transactions by default.  Have a look at AcceptToMemoryPool in src/main.cpp, and associated checks.  With no provisions against denial of service attacks, I can't see how bitcoin will survive in the long run, and of course bitcoin has to adapt to new attack vectors.  The rules do not change the validity of the transactions, only your willingness to relay and mine the spam.

I'm using extreme to get a point across. Everyone agreed Sybil Attack were attacks not choices. So unless you think that there was noting wrong with doing that you should use same critters with antispam rules that disrupted wallets...
