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? $\begingroup$

Stack Overflow: Here s what happened when we were hacked back in 2019

Developers have lessons to learn from the incident, too. Image: Getty Images/iStockphoto 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.

Stack Overflow 2019 hack was guided by advice from none other than Stack Overflow

Vulnerabilities in build systems, secrets in source code: developer environments are an attack target Tim Anderson Wed 27 Jan 2021 // 19:31 UTC Share Copy Developer site Stack Overflow has published details of a breach dating back to May 2019, finding evidence that an intruder in its systems made extensive use of Stack Overflow itself to determine how to make the next move. At the time, the company reported that an unauthorised person had logged into its development system and escalated their access to the production version of stackoverflow.com. The source code for the site as well as the names, IP addresses and email addresses of 184 users was stolen, but not the databases which contain the content of the site and that of its customers.
