Why is it a bad idea to filter by zeroing out FFT bins?


Why is it a bad idea to filter by zeroing out FFT bins?
$\begingroup$
It s very easy to filter a signal by performing an FFT on it, zeroing out some of the bins, and then performing an IFFT. For instance:
t = linspace(0, 1, 256, endpoint=False)
x = sin(2 pi 3 t) + cos(2 pi 100 t)
X = fft(x)
X[64:192] = 0
y = ifft(X)
The high frequency component is completely removed by this brickwall FFT filter.
But I ve heard this is not a good method to use.
Why is it generally a bad idea?
Are there circumstances in which it s an ok or good choice?

Stack Overflow, a popular site among developers, has revealed more about a week-long breach that it disclosed in May 2019. 
Stack Overflow said at the time that the attackers accessed user account data, and now the company says that after consulting with law enforcement, it can reveal more about what happened and how a newly registered user came to have moderator- and developer-level access.
Last year, Stack Overflow said it had identified privileged web requests that the attacker made that could have returned IP address, names, or emails for a very small number of Stack Exchange users. ....
