Can you help me intrude into/exploit (so-called “crack” or “hack”) someone’s server/instagram account/IRC account/Twitter/Facebook/etc.?
No, and that is because I am not a computer intruder or a “cracker”, and even if I were versed in that, I wouldn't try to get myself and other people in trouble by trying to exploit vulnerabilities on useful, ethical, services.
There are better ways to handle your online problems than to try to do cracking. For more insights, see:

Q: How can I break into/read/monitor someone else's email?
A: This is cracking. Get lost, moron.
Q: How can I steal channel op privileges on IRC?
A: This is cracking. Begone, cretin.
