Should I block a harassing collector, or keep the line open for records?

Last updated: 2026-07-12 · Educational content; not legal advice.

Short answer

Preserve the evidence first, then block if you need peace — because the harassment itself is the violation, you want screenshots, call logs, and recordings saved before you cut off any channel. Blocking a number is completely lawful, does not erase or admit the debt, and is not a waiver of anything; the trade-off is that a determined collector may just switch numbers. A stronger step than silent blocking is a written cease-contact demand, which creates a record and, if they ignore it, strengthens your SEC MC 18 (2019) complaint. Many people keep one written channel (like email) open for any legitimate notice while blocking the abusive calls and texts.

Frequently asked

Does blocking a collector waive or cancel the debt?

No. Blocking a number is lawful, admits nothing, and waives nothing — it only stops that channel. The debt (if valid) stands, and your protections against harassment stay in place.

If I block them, won't I lose my evidence?

Only if you block before saving it. Screenshot the messages, export call logs, and back up recordings first; then block. See /answer/how-do-i-build-a-harassment-evidence-timeline-for-a-complaint.

Is there something better than just blocking?

Yes — a written cease-contact demand creates a paper trail and, if ignored, strengthens your SEC MC 18 complaint. Many people keep one email channel open for legitimate notices while blocking abusive calls and texts.
