Answer 3

Generate any exception by checking the number of entries from the database or log.
For example, get the total number of records (total) before any data addition: a=total/(102/2-1-total);
After 50 records, everything will fall with a division by 0 error and then the code will not be executed: the counter will stop exactly at 50.
PS: Use only as a last resort!

It may be easier to come up with a project installation. The project is standardly written to the machine. Further, any unique data is taken from this machine. The code is then encoded with this unique data. At each start, decoding and launching occurs. Not 100% secure, but someone will have to pay for the hack. When changing the code, complete removal, so that they do not climb with their hands.
