Ugh, how frustrating for you. I have been really fortunate and haven't received anything like this. But maybe this is because people don't read my writing and feel a deep connection and an urge to get to know me better, like they do with yours.
But, it is peculiar that they feel they are "special" to take up your time with a personal message and expect to build a connection that way.
UGH. Keep doing what you are doing. Ignore, Block, Report.
It's only happening because you are awesome. But I appreciate that is no consolation in itself.
