Let's say that i have a hyperloglog in redis which counts messages is there any provisions whereby I can to some degree account for delete messages?

HyperLogLog is a data structure available in Redis that is used to count the number of unique elements in a set using a small, constant amount of memory. The element count is approximated with a standard error of 0.81%.
No, the HyperLogLog doesn't support the concept of deletion. Instead, use a different counter (could be an integer, Set or HyperLogLog) and subtract the totals.
