If they control the checksum check they can alter it too. Maybe, if you are careful enough to store all the checksums of everything you do online you will be able to tell, but others that see your posts won't even notice.

Merkle trees can help here. Basically a tree of hashes. If you keep track of the root hash, it's easy to prove any individual leaf has not been altered.
