No. But it may be a problem identifying each payment (the labels in your wallet won't be restored) and your privacy (each one of the 200 people who paid you can now see the 199 other payments that belong to you).
Maybe the user has forgone privacy to reduce future transaction fees by payment batching and utxo consolidation.
It's not really forgoing privacy as the user can always scramble the transaction outputs with JoinMarket or a mixer after consolidating all of the outputs.
Actually it would be quite annoying to obfuscate a bunch of dust transactions by sending them all together to a obfuscation service (it's technically a "double-fee").
